Electricity

Solar Data Treasure Trove

by

I have not kept it secret that I’m a fan of solar power. Leaving storage hangups aside for now, the fact that the scale of available power is comfortably gigantic, that perfectly efficient technology exists, that it’s hard-over on the reality axis (vs. fantasy: it’s producing electricity on my roof right now), and that it works well almost everywhere—what’s not to like? Did you trip over that last part? Many do. In this post, we’ll look at just how much solar yield one may expect as a function of location within the U.S.

Indian grid failure offers lesson to us all

by

In the US we may be staring at our own fate in India’s crisis. I’d suggest getting ready for it to come to a neighborhood near you sooner rather than later. Even the recent derecho was a reminder that, in fact, electricity doesn’t come from the switches on our walls, and that even our grid can look like spit balls and duct tape when an angry Mother Nature comes calling.

Our current infrastructure was built for a different planet

by

It’s easy to forget that every piece of our current infrastructure–roads, rails, runways, bridges, industrial plants, housing–was built with a certain temperature range in mind. Our agricultural system and much of our electrical generating system (including dams, nuclear power stations and conventional thermal electric plants which burn coal and natural gas) were created not only with a certain temperature range in mind, but also a certain range of rainfall.

Clean Energy Access For All – Grameen’s Solar Success

by

In one of the poorest countries on the planet a renewable energy service company is installing one thousand solar home systems – a day. Not in its capital or busy urban centers, but where 80 percent of the population lives – in rural Bangladesh. The company, Grameen Shakti, literally translates as rural energy. By the end of the year it will have installed a total of one million solar systems and now has expansion plans to install five million systems by 2015. Shakti is succeeding where business as usual has failed, and in the year of Sustainable Energy for All, it’s a success story we should all know by heart.
