The Japanese architectural and engineering firm, Shimizu, has a solution for the climate crisis: Simply build a band of solar panels 400 kilometers (249 miles) wide running all the way around the Moon’s 11,000-kilometer (6,835 mile) equator and beam the carbon-free energy back to Earth in the form of microwaves, which are converted into electricity at ground stations.
London’s subway will be supplying green energy to warm up more homes around the borough.
A new project announced by the Islington council will redirect the heat from a Northern Line of London’s subway to vent to homes across the city, giving homeowners a new way to get through the cold season. The project will deliver cheap heating to 500 homes around the area. It will not only be saving consumers money, but also the environment from 500 tons of CO2 emissions.
The Great Energy Shift is happening in spurts and is starting in places like Arizona and Mississippi instead of coming from legislation in Washington. Last week two two utilities faced decisions on whether to fight the future or embrace it.
Homeowners who aimed their panels toward the west, instead of the south, generated 2% more electricity over the course of a day.
Solar panels should face in the general direction of the sun. You would think that would be easy to do. But most installers of solar panels, especially the ones for homes, follow conventional wisdom handed down from architects, which holds that in the northern hemisphere, windows and solar panels should face south.
The off-grid clean energy market is booming. Sub-Saharan Africa is seeing 300 percent compound annual growth in off-grid lighting; Bangladesh is putting up 30,000 to 40,000 solar home systems every month; and d.light, a for-profit seller of solar lights, recently reached its1 millionth customer.

Grid-Scale Energy Storage in North America 2013: Applications, Technologies, and Suppliers, author Chet Lyons spoke with dozens of energy storage CEOs and summarized their thoughts in a recent report. Below is an excerpt of his 311-page report, highlighting eleven common threads shared by energy storage executives.
Power plants, wind farms, and smartphones all suffer from the same basic ailment — they lack cheap, reliable, long-life batteries to store large amounts of energy for when the sun goes down, the wind stops blowing, or the device is unplugged for a long time.
In 2007, officials from Berkeley, California shut off the electricity to an artists space known as the Shipyard. That action, which forced the artists there to seek a new way to power their flamethrowers, is the origin story of a company that now produces what it says is the world’s only carbon-negative power source.
All of that electricity in a thunderstorm. All that lightning, all those kilojoules of power, just waiting to be harnessed, if only we knew how do it! Could we really harness the electricity from lightning?
