A channel in which algae is bred and gently stirred with a paddlewheel. Growing algae on sewage could generate affordable biofuels. To make this work you begin with a series of small artificial rivers where waste water flows and algae is cultured. In those ponds is a paddle wheel, which pushes the water about and [...]

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 [...]
Global consumption of natural gas will rival the use of coal and steal the market share from oil on the world market. The “next defining energy trend” is poised to be natural gas as it increasingly becomes a primary global energy source, according to a report released today by GE.
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 [...]
Train carrying coal to a power plant. 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 [...]
Off-grid solar 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.

Hundreds of companies are investing in electricity transferred through magnetic fields. Nikola Tesla, the inventor and rival to Thomas Edison, in the early 1900′s built the Wardenclyffe Tower, a 187-foot-high structure on Long Island, which he said could transmit electricity wirelessly. Financier J.Morgan backed the Wardenclyffe Tower. The project failed, and Tesla ended up broke. [...]
What are energy CEO’s thinking? 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.
Wind power could generate as much as 18 percent of global electricity by 2050. Wind energy only accounts for a small percentage of global electricity production even though we have seen more wind farms popping up over the last few years. Wind power generates only 2.6 percent of the world’s electricity, according to a new [...]
