Response: What’s the deal with the Clean Power Plan?

This is a neat article, Holly, and it’s funny because there’s a lot of overlap between this and the one I just wrote about the RNC’s recently released environmental platform. After reading up some more on this debate, it amazes me how so much of the power and control in this country’s judicial system is achieved through lawsuits and stalling.

 

A new point that I’d like to bring into consideration is the fact that out of the 24 states suing, the ones at the forefront of this case are also the ones that produce the highest amounts of coal, and CO2, in the country. The case is called “State of West Virginia, et al. v. United States Environmental Protection Agency, et al.,” after all, and West Virginia is the nation’s 2nd largest coal producer, accounting for 11%. The main power—pun intended—behind this suit comes from those who are litigating as petitioners. Those petitioning against it are almost all hiding behind the guise of trade associations that they are members of. What happens is, the power companies become members of various trade associations that lobby on their behalf, and their membership does not have to be made public. So when those associations petition the courts, their funding comes from the countless power companies privately associated with them.

It’s a legal swamp that’s being plunged into—the case is the consolidation of 38 separate cases—and some that belong to trade associations, such as Dominion Energy, have actually voiced support for the CPP. Although Dominion is one of the large producers of fossil fuels, it also seems to be gearing for a shift toward renewable alternatives. They were, after all, the ones who provided the majority of the funding for Jennette’s Pier’s wind turbine project. While their renewable initiatives are likely rooted in self-interest, it is a promising sign when large power companies start to move toward the bandwagon of cleaner alternatives. The day that companies realize that coal is more of a financial risk than investment and renewable energy is an advantageous side to be on, is the day that we will start a global transition to clean energy.

Because of how we are set up democratically, our courts allow (ideally) for everyone to be heard equally. The problem with this is that groups with access to exorbitant resources manage to overpower and stifle those they don’t agree with, thus trampling on their right to be heard, but all 100% legally. Hopefully, when the court hears oral arguments starting September 27th, 2016, the voices of reason will be heard just as clearly as the voices behind pollution.

As Will outlined in his blog post Tesla’s New Master Plan and the Future of Electric Cars, Elon Musk has been successful in implementing his four step plan to further the electric car industry. Musk’s plan may be brilliant, and the benefits could even reach further than most anticipated. Of course, there are some social and practical challenges that must be overcome before everyone is cruising in their own electric cars.

The expansion of electric vehicles has the obvious benefit of decreasing the air pollution that come from exhaust pipes. Some argue that everyone driving electric cars isn’t the saving grace if much of the electricity is being generated from fossil fuels. Though this must be taken into consideration when considering Tesla’s success, it is important to note that the burning of fossil fuels in a car is far less efficient than doing so at utility scales.

Tesla’s electric cars will be most effective when used in conjunction with other sustainable technologies. For example, an electric car could be used as an energy-storing device for a home fitted with renewable technologies like solar or geothermal. The electric car could harness the excess energy created by residential installations or reduce demand during peak-demand by charging at night.

This reality may be several years away, but progressive legislation could speed up the process. Places like California are already paving the way to sustainable growth and development. The states cap and trade system has pushed energy providers to invest in cleaner technologies. Though funding may be running out, the Clean Vehicle Rebate Program helped put thousands of new electric cars on the road. Businesses have economic incentives to build charging stations with the tax credit that California provides.

The list of policies that favor green technology is extensive, but many states are still stuck in the climate change debate. If President Obama’s Clean Power Plan is able to move forward, perhaps electric vehicles could be a jumping off point for many state carbon reduction plans.

Tesla’s New Master Plan and the Future of Electric Cars

Published by under Student blog entries

In 2006, Elon Musk released his first Master Plan for  Tesla Motors, Inc. while he was still just on the board of directors. At this time, the Roadster had yet to be released and the idea of financing an electric car company was considered laughable in the industry. He laid out a four step plan that was based around providing an inexpensive electric car through the sale of expensive ones that will gradually drive the price down to one that everyday Americans can afford. Once the Roadster was released, it became a novelty item for those that could afford it, a unique car for the rich to collect.

And then the Model S dropped, resembling a mix between KIT from Night Rider and the StarShip Enterprise while also not completely breaking the bank. No longer were electric cars those ugly boxes driven by your hippy neighbor, instead its a luxury car that causes onlookers to drool in envy. In 2015, the Model S became the #1 best selling plug-in car, selling over 50,000 cars around the world.

10 years later, Musk releases his second Master Plan which highlights a new direction for the company. Now that Tesla can provide a relatively cheap electric car, with the soon to be released Model 3, the focus can be placed on improving this technology to the point where it would be dumb not to drive on of these cars. The new plan, as he puts it, is:

  1. Create stunning solar roofs with seamlessly integrated battery storage
  2. Expand the electric vehicle product line to address all major segments
  3. Develop a self-driving capability that is 10X safer than manual via massive fleet learning
  4. Enable your car to make money for you when you aren’t using it

These ideas are not just important for the next wave of Tesla cars, they’re going to make advances in other fields. The work and innovation required to build the kind of solar panels that Musk wants on his cars will lead to more efficient solar panels and better battery storage systems. The self-driving car will be a major breakthrough and represent one of the first implementations of A.I. in a system that will define the future of automotive transport.

The large car companies have been scrambling to find something to topple the giant that is Tesla from the electric throne, with exciting results. The new GM Bolt intends to be released at $30,000, $5,000 cheaper than the Model 3 with the same 200 mile range. This new Master Plan, and the one before it, outline an ambitious strategy that has sparked intense competition as a result. This kind of competition can only be good for the consumer, driving down the price of electric cars while also putting a focus on energy technologies.

Much like Elon Musk’s other investments into SpaceX and the Hyperloop, the success of Tesla is not measured in dollars. Musk decided that because we “must get off fossil fuels anyway and that virtually all scientists agree that dramatically increasing atmospheric and oceanic carbon levels is insane, the faster we achieve sustainability, the better” (Musk, 2016) and invested his own money to drive a much needed industry forward. When we are all driving automated electric cars within the next ten years, we will have Elon Musk to thank.

The Grand Old Party: Not so Grand for the Environment

The Republican Party just released its platform on July 18th, which details its principles and policies to help guide the public during this election season. In order to get a heads-up on what Donald Trump—the Republican National Committee’s (RNC) presidential nominee—might do if elected President, Live Science examined the party’s platform, as well as the scientific research behind each stance. Then, they put together a handy guide that details each issue, the RNC’s stance on it, and the scientific research that either backs it up or contradicts it. For the sake of objectivity, they will be going through the same process for the Democratic National Committee’s (DNC) platform that was released on July 21st.

What the comparison reveals is a long list of ways that the RNC plans to derail environmental conservation efforts. It is clear when reading the RNC’s statements that they see no imminent threat to the environment caused by human actions. Therefore, they see no need to enact legislation to protect it. Their statement on the Keystone XL pipeline is as follows: “The current President’s job-killing combination of extremism and ineptitude threatens to create a permanent energy shortage. We are committed to approving the Keystone XL Pipeline and to streamlining permitting for the development of other oil and natural gas pipelines.” The pipeline would carry tar sands oil from Alberta, Canada to Nebraska—its coverage would total 2,639 miles. The science behind whether or not the Keystone XL pipeline hurts the environment does not coincide with the GOP’s stance. In 2015, the Environmental Protection Agency (EPA) commented on the proposal, stating that if the pipeline were to run at full capacity, its yearly greenhouse gas (GHG) emissions would be equivalent to putting an additional 5.7 million cars on the road. The project would also require the tar sands to be processed at a carbon reservoir in Alberta, which would release large amounts of GHGs into the atmosphere. This would make it pretty unlikely that the international goal of preventing the Earth from warming more than 3.6° F would be met.

The scariest part about their new platform is the fact that they refuse to acknowledge just that—facts. Under the GOP’s “Protecting our Environment” section, the first line actually claims that “the environment is getting cleaner and healthier.” Not according to countless studies conducted by the UNEP, NASA, and the Union of Concerned Scientists, to name a few. Although they do acknowledge the need for renewable energy, they don’t seem to be in any hurry until the already-established oil, nuclear, and natural gas companies have come up with their own technology to do so.

After reading the GOP’s platform, it is clear to me that there is a blatant disrespect on their part for the scientific community as a whole. The GOP has long fought to discredit any scientific findings that don’t align with their political agenda. Whenever science—which is so heavily peer-reviewed and self-correcting—interferes with their opinions, they simply refuse to listen. Science says that gravity is a real thing? That doesn’t threaten their beliefs, so they allow that to be put in the textbooks. Science says that climate change is a real thing? They stand behind Lamar Smith, a Republican chairman, as he accuses the National Oceanic and Atmospheric Administration of rushing and not properly peer-reviewing a study they published about climate change. The fact that a Republican chairman, with his only scientific background being that he took basic science courses in college as part of his non-scientific degree in American Studies, can rightfully challenge an entire group of some of the most educated and accomplished scientists out there is worrisome and insulting to science as a whole.

The whole purpose of checks and balances is so that no one branch can become too powerful. But is that Constitutional system really working that well if one branch continuously attacks and attempts to dismantle the role and authority of the other?

Natural Gas: May Not Be the Bridge After All

Published by under Student blog entries

A study recently done by researchers at Purdue and Cornell universities focused on gaining a better understanding of the levels of methane that are emitted during the removal process of natural gas from the earth. It was widely thought that natural gas would be the “bridge” fuel between coal based systems and renewable sources. It was marked as a cleaner fuel than carbon-rich coal, but not quite to the mark of the carbon-free renewable forms and thus would help in the transition process of shifting energy dependence from the former to the latter.

In a report from the IPCC, it was said that natural gas as a bridge fuel would only be effective if “few gases escape into the atmosphere during natural gas production and distribution” (Magill 2014). For a while, it was believed that this was the case that is until this recent study, and others like it, were published. They highlight an important flaw of the natural gas extraction process to be “fugitive” emissions that escape while a well is being drilled (Magill 2014). Methane emissions are the most common of the fugitive emissions which is alarming being that methane is 84 times more potent than carbon dioxide over a 20 year period (Magill 2014). The drilling process potentially emits up to 1,000 times the methane than previously supposed (Magill 2014). This number could be even higher considering other unknown factors of the quantification and distribution processes. Dana Caulton, a researcher from Purdue, said that emissions from drilling are completely left out of some of the EPA’s greenhouse gas inventories because it is “assumed to be negligible” (Magill 2014).

When the wells are being drilled, the natural gas that was contained in the shale layers is able to be released and then enters the atmosphere. Large amounts of natural gas are also able to leak out into the atmosphere via cracks and breaks in the distribution system. Fixing these leaks would not only be strenuous and costly, but also time consuming. This is definitely not ideal when considering that the IPCC also reported that we only have between 15 and 20 years for the natural gas “bridge” before our transition should be complete (Magill 2014).

It is not surprising that this method for providing energy has shown to be ineffective, given all of the already known controversies that come with natural gas extraction. With this new data, it is as important as ever for us to look towards renewable energy sources. Without this bridge, we no longer have as much time to carry out the lofty transition and must begin now if we hope make a positive difference in our efforts to combat global warming.

Discoveries from Disasters

Published by under Student blog entries

When the BP oil spill named Deepwater Horizon happened in 2010, BP set aside $500 million dollars for a private company to research its outcome and the overall environment it was affecting. With millions in the bank account Gulf of Mexico Research Initiative (GoMRI) funded the efforts of 1,200 scientists to monitor the gulf and its inhabitants.

One of the fundamental discoveries that were made by observers were the paths of the oil itself. The oil did not follow some of the large currents that satellites had identified as the mainstreams in the gulf. This at first puzzled the scientists, but also gave them a chance to monitor and notice come medium sized currents that had never been available to the human eye because of the oil that was traveling by the currents. As many scientists will state, research and understanding is often limited by the mechanics and devices they deploy, and also human observation.

DriftersThrough the deployment of cheap drifters, the scientists were able to measure some of the first smaller currents in the gulf. This discovery was a success for the team as they tracked the sub-mesoscale currents.

As many people during the oil spill were concerned with mammals and other viewable aquatic animals, the scientists were more concerned with the effects the spill was having on more primary animals including zooplankton and insects. While many of these animals go unnoticed, some of them are the habitat builders and he foundation of the aquatic food web. The oil spill created an opportunity to broaden the scope of creatures being tracked and counted, and putting some species on the map for the first time in history. They have identified at least fifteen new organism since the oil spill, and can now begin to track the effects of these organisms in the environments and also the effects of the oil spill on the organisms themselves.

Another discovery that was noted of worthy of investigation was natural oil seeps. The oil that the companies are tapping into for human combustion also have natural seeps that leak up to 1.4 million barrels of oil into the waters every year.  These reservoirs that are leaking are feeding grounds for many microbes that are at the base of the food chain. The microbes that digest the hydrocarbon-rich oil are then preyed upon and create a thriving unique environment that scientists study by videography. The film is used to understand the process of the oil leaking, and contributing factors to the oil release. These sites are not only important to understand because of the oil leaks, or the animal life, but because of the crystalline formations of methane, that are a potential climate change impact if enough methane is collected in the marine environment. These formations are poorly understood, and the spill allowed for dedicated time and efforts to be focused on the formations to understand their future and current hazards.

The Dangers of Ignorance

Published by under Student blog entries

Last year, December 2015, President Obama passed a bill that officially banned micro-beads in the United States (Imam, 2015). The purpose behind this bill was to protect the waterways of the country since water filters were unable to catch the minuscule exfoliating beads as they traveled through the underground sewage network.

Some cheered for this victory in environmental protection and others were disappointed by the discontinuation of their favorite skincare products. I, on the other hand, was just surprised because I had never even thought that my hand soap or face-wash could have a negative environmental impact. I was ignorant. In hindsight, it was clear that the beads were not good for the natural environment since they were plastic and non-biodegradable.

Though micro-beads are now banned, there are still plenty of everyday products that we use without thinking that damage the home that we are trying so hard to maintain and protect. If you use either sunscreens, moisturizing lotions, lip balm, lipstick or other similar cosmetic products then you might be playing a part in the death of around 3 million sharks a year (Lima, 2016).

In the liver of these deep sea sharks is an organic compound called Squalene. Squalene is coveted and utilized by the cosmetic industry due to its softening effect and non-greasiness (Lima, 2016). Some companies have switched over to the more sustainable plant-based Squalene, but not all have done this since plant-based Squalene is more expensive (Yeomans, 2012). Due to the demand for the cheaper shark-based Squalene, shark populations are taking a hit from being hunted for their livers (Lima, 2016).

There are several simple things that we can do in order to make sure that we do not play a part in the shark hunt.

  1. Read the labels! If the labels do not specify where the Squalene originates from then call and ask the supplier.
  2. Share the news and do not buy products from suppliers that support shark liver harvesting.

Just as environmentally damaging products and actions may sometimes be as obvious and big as an oil spill, they can also be as small as the micro-beads that used to be in most face-washes. It is up to us to be aware of the things we are using and their implications. Ignorance should not be an excuse in this day and age.

Big Winds Blowing in the Big Apple

Published by under Student blog entries

The winds of change are howling in New York. (Frabz.com)

After 130 years of worrying about making a good first impression, Lady Liberty might soon get some relief.

Before catching a glimpse of the iconic green lady, weary travelers sailing into New York could now be greeted first by iconic green energy: offshore wind turbines.

In the next 24 hours, the Long Island Power Authority (LIPA) is expected to approve the South Fork Wind Farm.1  The 90 MW, 15-turbine wind farm would sit in the Atlantic Ocean, east of Montauk, N.Y.2

When complete, South Fork could generate power for 50,000 homes in the Hamptons.2  Likely taking a cue from Cape Wind’s controversy, developers emphasize that turbines will be placed 30 miles offshore — over the horizon and out of sight from land.1

The project will be built by Deepwater Wind, which will open the nation’s first offshore wind farm off Block Island, R.I. this fall.3  That smaller, 30 MW project took seven years to develop4, but “probably shaved three years off of [South Fork’s] development time”, LIPA CEO Thomas Falcone told Politico.5 Because both projects are located in the same federally-approved waters, he expects South Fork construction to be expedited, with power reaching Long Island customers by 2022.2

And that’s just a start. South Fork is only the first phase of a planned Deepwater ONE Wind Energy Area, spanning 256 square miles between New York and Massachusetts, with a potential for more than 1,000 MW of power.

Two years ago, LIPA rejected a separate proposal for a 200 MW wind farm off Long Island due to an estimated $1 billion cost.  However, New York governor Andrew Cuomo’s new goal to power the state with 50 percent renewable energy apparently forced LIPA to reconsider.6

Back on the table is another site: a 127-square mile Wind Energy Area (WEA)2, sitting 11 miles south of Long Island’s popular Jones Beach, which could produce 350 MW.7  Federal officials plan to auction offshore wind rights to “The Wedge”2, but conflicts with scallop fisheries, shipping lanes, and even high-frequency NOAA radars pose hurdles.7

Undaunted, Deepwater Wind CEO Jeffrey Grybowski says “there’s real momentum for offshore wind in the United States”,8 and proponents say 2016 could be “the year” offshore wind finally takes off in the U.S.9  It’s far behind the 12 GW of offshore wind capacity already installed elsewhere in the world (90% in Europe)8 , but it’s a start.

Update: LIPA trustees’ scheduled vote to approve the South Fork wind farm this week was postponed.  Offshore wind enthusiasts, stay tuned.

Adélie Penguins: A new Species to Keep an eye On

Along the rocky coastline and ice-covered waters of the Antarctic, lives the penguin species Adélie. These waddling fellows can be distinguished from their counterparts by a vivid white ring around their eyes. Adélies make up a large portion of the penguins in the Antarctic region, but recent studies have their numbers dwindling by up to 60% in the next century (Cimino et al., 2016).

Those who still refute the data backing climate change love to use snow days as a defense for their argument against its existence. Because the Earth can’t possibly be warming if there’s still snow, right? What they don’t understand is that with climate change, comes abnormal weather patterns. The whole natural scheme of things is being thrown off, delaying seasonal cycles and creating erratic precipitation patterns (Parry 2012). Global data have shown that, despite the occurrence of snowfall and chill, the global surface temperature has been increasing (NASA).

Climate change and its weird seasonal shifts are putting stress on the Adélies’ instinctive nesting patterns. Adélies only nest on bare, dry land, but higher levels of precipitation and snowmelt, due to novel climate, create large pools of water, which can drown the chicks (Cimino et al., 2016). The rising temperatures, while undoubtedly harmful to most all Arctic life, were initially thought to be a benefit to the Adélie, due to their nesting requirements. But the temperatures have begun to rise outside of even their habitable range. The sea surface temperatures, along with the sea ice concentrations are not at the levels they need to be to sustain the large number of Adélies in the region.

 

Most everyone probably learned in the third grade or so what the three things most essential to survival are: water, food, and shelter. We already covered their shelter situation, and anyone who knows how to read a map can see that they are not suffering from lack of water—the Antarctic ice sheet contributes about 61% of all fresh water on earth, and it’s melting!—but what about their food supply? The Adélie’s two main sources of food, the silverfish and the krill, have both been experiencing declines due to the same Antarctic sea changes. Both the silverfish and krill require specific water temperatures for nesting and survival, but with the increase in temperatures and fluctuating sea ice concentrations, they’ve had to migrate elsewhere (WWF). This leaves the Adélies to find new food sources that are in ample supply. When a food source leaves an area, many species move with it, but Adélies have specific nesting patterns that limit their migratory flexibility (NPR).

 

The Adélies’ struggle to adapt is just one of many examples of species around the world struggling with the ramifications of climate change. The process of evolution is designed to allow species to adapt to changes in their environments, but the speed at which climate change is changing things is much faster than most species can adapt to.

Out of the Dark and into the Light- Coal and Solar Energy

Certain small coal mining towns fight any threat to their mine(s) which may or may not be the town’s main way of gaining sustenance. This is quite possibly the way they have operated ever since the industrial revolution, and while there have been many safety advancements, coal mining continues to be a treacherous occupation (Gibson). Coal no longer is the “cheap” energy source as natural gas and other renewable energy sources take center stage. However, it is tough not to sympathize with coal mining towns as they make the transition into a world which is less dependent on coal.

The coal industry is in a strong downturn due to many factors within the economy (Fehrenbacher). However, the light at the end of the tunnel may be the very energy that is in part responsible for forcing coal into decline: solar energy. Increased construction of solar farms may solve the employment problem for miners as they trudge out of the floundering coal industry (Pearce).

Even though solar energy and coal energy seem to be complete opposites, they can definitely benefit from working together. Coal miners exposed to less harmful particulate matter and working on safer job sites will be less likely to experience the detrimental health effects of coal. Providing this open window to the future may convince people who resist change in the energy sector to accept solar energy with open arms. In America’s market, jobs often do the talking.

Solar panels seem like the easiest way to harvest renewable energy. The technology has been developed, and installation, compared to other renewable energy sources, is relatively easy. Radiating energy from the sun is there for the taking. So why don’t we construct more solar farms? The simple answer is economics.

Ever since the industrial revolution, America’s economy has been centered around fossil fuels. The transition from fossil fuels to any source of renewable energy shall be a rocky one, but there is a growing necessity to find more energy sources to meet the hungry demands of modern America. Harvesting solar energy has become so efficient that the price differences are astounding (Nunez).

On the other hand, economic investments in the solar energy sector are still seen as risky as they have not been proven to provide a consistent return. Tesla’s buyout of SolarCity is one such example of a transition to a green economy considered to be a risk (Musk). The economy is not receptive of such transitions and will most likely resist these changes at first. Investors putting money down now are taking a risk, but not as much a risk as investing in an energy resource with a finite supply.

The word coal has a negative connotation for much of the American public. It is dark, it is sludgy, and it is a wide source of pollution. Acid rain from coal fire plants in Tennessee is causing degraded habitats in the North Carolina mountains. Coal ash ponds rupture and leak on a much to regular basis, but coal fire power continues to be supported by subsidies only because the economy is on auto-pilot. The sun conjures up images of summertime and children playing outside. Pollution is produced in small quantities by solar panels, compared to coal fire power plants that emit pollution during construction, operation, and decommissioning. The future of America is bright, not only with potential, but with the glowing solution of solar energy.
