Wind Can Supply 20% of U.S. Electricity, Report Says
Solar Energy; Not Just Electricity
A common inaccuracy that I frequently encounter -- through work, in the media, and in government -- is based on an implied assumption that energy, and energy displacement, and therefore solar energy, revolves solely around electricity. This perception is pervasive in several countries around the world.

Smart Power Strips the garlic of Electronic Vampires
...a technology available right now that can make some wanton energy waste history. It’s a surge protector that stakes the hearts of vampire electronics without hassling you, the sleeping victim.
Video -- Energy Down Under: A Look at New Zealand
New Zealand's isolated geographical location has lead to an energy portfolio that contains a large renewable energy mix. Electricity is generated mostly from hydro and geothermal energy. Wind is a growing energy resource. For transport, New Zealand relies on oil imports. No wonder that the New Zealanders are interested in exploring electric or fuel cell vehicles, with the electricity and hydrogen generated in New Zealand in an environmentally friendly way.
Video: Wind Energy Industry Leaders on Future of U.S. Wind Power
U.S. wind power is growing at a breath-taking pace. Representatives from top wind turbine manufacturers including GE Energy, Gamesa, Siemens and Vestas, discuss U.S. wind energy's future outlook.
How conserving electricity is bad for the environment
If you think saving electricity the traditional way (by turning stuff off) is good for the environment you may be wrong.
Video: Smart, Green Cities Conserve More Energy Than all Alternative Sources Combined
Rather than expanding current wind and solar power sources, energy experts indicate it is more crucial to eliminate and restructure current consumption methods. Jim Sweeney, an energy economist from Stanford University, says "freeing up 10 percent of current demand would leave more energy available than expanding all current wind and solar production tenfold." Echelon, a Silicon Valley-based company, indicates certain areas known as "smart cities" are doing this using networking technology.
Dean Kamen's Water Regenerator; Makes Water out of Wine
We like to pay homage to Earth Day as much as we can (stretching it on to the next day and beyond) and so we give the stage to the inventor of the Segway, Dean Kamen. He has come up with a device that will turn any liquid into drinkable water and despite its huge non-prettiness and using cow dung as fuel, I think we all can appreciate that people will be able to drink who couldn't before .
Changing your Electric Meter to Save Electricity
Is your electric meter as old as the hills? If you are like the majority of people, your electricity meter is most likely is over half a century old. You need to change it or get it changed.

Video: Builder Turns To Modular Eco Structures
For 35 years, John Garlow of Monongalia County, WV, has run a framing business, primarily for modular homes, and he's still doing that, but he's changing his ways. Last year he started a business called EcoStructures. His goal is to build affordable modular homes that are completely off the grid, homes he says would sell for $100-$200K. Garlow is building his first EcoStructure.
Chevy Volt’s Lithium-Ion Batteries Road- Tested By Month’s End : Gas 2.0
GM’s plug-in hybrid electric car, the Chevy Volt, will have its lithium-ion batteries road-tested by end of the month. Engineers have already been testing the Volt’s electrical hybrid system, the so-called E-Flex architecture, but only with nickel-metal hydride hybrid batteries in place.

Why green electricity prices go up when brown prices do | Energy Sector | Zerocarbonista
From the page:
"I often get asked to explain why the price of green electricity rises when the price of brown electricity does. I realise it’s counter intuitive. To understand it you need an understanding of how the market works. Here’s my attempt to explain"

Solar Thermal Electricity: Can it Replace Coal, Gas, and Oil?
One of the most common arguments against large-scale use of renewable energy is t hat it cannot produce a steady, reliable stream of energy, day and night. Ausra Inc. does not agree. They believe that solar thermal technology can supply over 90% of grid power, while reducing carbon emissions.
