Global solar power surged in 2011 – 73% growth

2011 was a great year for solar power with an increase of 73.3% in generating power – the fastest growth since reporting began. Germany and Italy led that charge by installing 57.1% of the new power. Worldwide there is now 63.4 gigwatts (GW) of solar power – of which 29.3 GW were brought online in 2011. …

Tesla announces network of free charging stations powered by solar energy

The biggest problem with driving an electric vehicle (EV) is not driving from home to work. It’s the long trips and vacations that scare people – beyond the EV’s range of 75-150 miles per charge. They need a network of charging stations, like gas stations, placed along highway routes for all the popular destinations. And …

The first high performance – ultra energy-efficient – residence hall

A Passive House certification is one of the highest available for energy-efficient homes. And this residence hall in Belfast, Maine demonstrates that, “space heating costs for TerraHaus are less than $300 per year ($30 per student), a big improvement from the two poorly insulated housing units it replaced, each with an annual space heating cost …

European Solar Decathlon – Solar home creates twice the energy it uses

Our homes were never designed for energy efficiency. So what happens when designers, architects, and engineers approach the problem? From the European Solar Decathlon: “The house generates twice as much energy in Hungarian conditions and three times as much in Madrid as the house itself spends,” the Odooproject team states. “This amount is able to …

The future of street lights – hybrid power with mini-wind turbines & solar panels

A friend recommended these to me after her company installed them. From UGE, they are streetlights combining solar panels with mini-wind turbines. They are quite amazing: From the brochure (pdf): Our hybrid model operates entirely off-grid. Can be installed in remote locations which are inaccessible to the electric grids. Lower utility costs – avoid the high …

Wind is cheaper than coal? — Fact checking this statement

The other day I heard in passing, “wind is now cheaper than coal.” If true, this symbolizes the holy grail of renewable energy. It would mean that a turning point for not only cleaner energy, but global warming, climate change, pollution, foreign oil dependence, and more. To fact check this, I pulled up the top …

Crowdsource the launch of a nano-satellite into space – Kickstarter

We are developing a nano-satellite, and mobile apps to go with it, as the focus for a global education and public outreach campaign. The satellite, called SkyCube, is a 10x10x10 cm “1U” CubeSat intended for launch as a secondary payload on a SpaceX Falcon 9 rocket in 2013. Orbiting more than 300 miles up, on a …

8 clean energy predictions from a decade ago…that were way wrong

From the Fresh Energy blog and a good reminder that most experts have trouble thinking exponentially.   WIND In 2000, the International Energy Agency (IEA) published its World Energy Outlook, predicting that non-hydro renewable energy would comprise 3 percent of global energy by 2020. That benchmark was reached in 2008. In 2000, IEA projected that there would …

A refreshing look at climate change in America – what are we doing about it?

A refreshing, well-balanced look at climate change in America.   You don’t have to be a climate scientist these days to know that the climate has problems. You just have to step outside. The United States is now enduring its warmest year on record…Meanwhile, the country often seems to be moving further away from doing something …

Energy Department invests millions to accelerate high-volume solar manufacturing

A $25 million federal grant will speed the construction of a solar manufacturing plant in San Diego, in an effort to boost U.S. competitiveness. Semiconductor maker Soitec Solar, recipient of the Department of Energy grant, will pour the funds into equipment at its Rancho Bernando-area plant. Production is set to start before the end of …
