U.S. Tidal Energy Firsts

On July 24, 2012, the first commercial, grid connected tidal energy project in the United States was deployed in Eastport, Maine on Cobscook Bay.  In Cobscook Bay, tides often vary by about 20 feet over a twelve hour period and water flows at about 6 knots when tides are strongest.  According to current estimates, Alaska […]

While multiple European countries seem to be heading in the right direction regarding renewable energy, it appears that Great Britain recently took a step backwards. The British government dealt the renewable energy a blow by cutting subsidies for multiple industries.  Although leaders in the renewable industry view the new policy as detrimental to the future […]

Mixed Signals in Europe’s Offshore Wind Energy Progress

Published by under Student blog entries

Although Europe has been struggling economically, developers in the region have substantially increased the amount of wind turbines attached to the grid just this year. They have already connected 132 turbines, totaling up to 523 MW of increased installed capacity. Up to 160 more turbines have been assembled, adding up to 647.4 MW, but the […]

Drones Devour Drifting Debris

Pollution is piling up in the ocean. Land based sources cause up to 44% of pollutants entering the sea, and the atmosphere takes responsibility for 33%. Maritime transport is the source of 12%. Scientists are working to develop new methods for ocean clean up, one being the employment of drones. Drones are self-sufficient devices performing tasks otherwise requiring […]

Fish Populations Experience Increase in Number around Danish Wind Farm

Published by under Student blog entries

While the number and size of wind farms increase, research on the environmental effects of this source of renewable energy becomes more important. One of the main concerns with wind farms is its effects on fish populations. While most externalities of energy generation seem to be negative, there has been speculation that that wind farms […]

Fertilizing the Ocean with Iron

Published by under Student blog entries

http://flic.kr/p/KjEZ   Geo-engineering is a term that will probably become more apparent in the coming years. An experiment done in 2004 in the Southern Ocean has shown some advancements in the concept of dumping iron into the ocean in an effort to remove carbon dioxide from the air. While this idea has been around for […]

Japan Pushes for Renewable Energy Sources After Fukushima Disaster

Published by under Student blog entries

While most of the world has moved on since the catastrophic destruction resulting from last year’s earthquakes and tsunami in Japan, the people of Japan are still suffering in multiple ways. Primarily, the meltdown of the nuclear power plant called Fukushima is still keeping over 70,000 people who lived within 20 km of the plant […]

Eagles Threatened by Wind Turbines in Scotland

In two separate instances this year – in May and June – the Royal Society for the Protection of Birds (RSPB) in Scotland have fought to prevent wind turbines from being installed in the Scottish Isles.  The wind resource in these areas is profoundly significant. “Scotland has the best onshore and offshore wind resources in […]

Floating Wind Turbines

Published by under Student blog entries

  In an attempt to develop better and more efficient sources of renewable energy, a few companies are working on a new type of wind turbine: turbines that float up in the air.  While several wind farms on land have proved to be excellent sources of energy, there are some issues.  At lower altitudes, winds […]
