Tidal turbines installed in Scotland

Scotland achieved a major milestone this week by successfully installing a 10MW tidal power array in the Sound of Islay, off the coast of Orkney.

World’s first geothermal-solar plant opens in Nevada

The Stillwater geothermal plant in Nevada has added a solar array and now provides 59 MW of clean, steady power. Geothermal produces power 24/7 while the solar provides extra power during the day when it is most needed.

Renewable energy substantially cuts water use

Power generation accounts for 39% of water usage in the US. Coal, natural gas, and nuclear power plants use the most amount of water while renewable energy like wind and solar photovoltaic use the least. Increasing competition for water coupled with current droughts make it all the more important to devise new ways to create [...]

Maryhill Museum: Artful wind power

This isolated museum, which sits on 5,300 acres located in Washington State’s Columbia River Gorge about two hours east of Portland, derives some of its annual income from leases for the 15 wind turbines that have been installed on its grounds, part of a huge [...]

US imposes huge anti-dumping tariffs on Chinese solar panels

The tariffs are anywhere from 31%-250% which could easily about kill the booming solar installation market here. Renewable energy does not need a trade war between two nations. Let’s hope this is just saber-rattling by the US. China could retaliate by raising tariffs on US polysilicon entering their country for use in creating solar panels, something [...]

Apple and renewable energy

Responding to criticism over energy consumption at its data centers from Greenpeace and other activist groups, Apple made an announcement on its website on Thursday, May 17, 2012:

Apple’s data center in Maiden, North Carolina, will draw about 20 megawatts [...]

Military biofuels: Penny wise?

The Republican-led House Armed Services Committee voted earlier this week to stop the Department of Defense from buying alternative fuels that cost more than fossil-based fuels. This would halt current US military programs that have been testing biofuels [...]

Wind power in Maine at risk due to inadequate grid

Central Maine Power Co.’s $1.4 billion transmission system upgrade isn’t designed to handle the power that can be made available at times from new and existing alternative energy plants.

This story is increasingly common. Renewable energy is widely distributed and can flucuate instantly in amounts of power generation, something [...]

City of Los Angeles making bumpy transition to clean energy

How do power companies transition from dirty energy to renewable energy while keeping the lights as they do it? The Los Angeles Department of Water and Power (LADWP) is finding out, as they work towards a clean, renewable energy future. What they are doing makes an instructive case study for other utilities, many of [...]

First offshore wind project in US cancelled. Sigh

Wind power company Gamesa has cancelled plans to installed a solitary wind turbine off the Virginia coast, citing regulatory uncertanties, lack of an offshore grid, expiration of tax credits, and difficulties in getting locations approved.

Other countries [...]
