A home battery that is cheap, durable, safe and as big as you like that could store solar or wind power is closer to reality. Harvard University researchers report that they have tested a “flow battery” that uses cheap and abundant chemical elements, can be operated with plastic components, will not catch fire and can operate at 99 percent efficiency.
On July 9th, Denmark’s wind farms produced 116% of national electricity demands, and according to The Guardian, that figure had risen to 140% by the next morning, allowing the country to export power to Norway, German, and Sweden.

This week Kenya set in motion the construction of Africa’s biggest wind power farm, near Laisamis, 550km north of Kenya’s capital Nairobi. Continue reading… “Kenya to generate a fifth of its power with Africa’s biggest wind energy farm”
Engineers from Stanford have developed a state-by-state plan to convert U.S. to 100% clean, renewable energy by 2050. Continue reading… “Stanford engineers’ plan for converting U.S. to 100% clean, renewable energy by 2050”
Nice Architect, a Slovakian company, has created the ecocapsule, a new kind of super green micro dwelling. The ecocapsule is powered by a built-in wind turbine and solar cells, and its egg-like shape allows the collection of rainwater and dew. Continue reading… “The Ecocapsule is a new super green micro dwelling”
“What if you could scoop the air? Scoop it and move it downward, amplifying its kinetic energy along the way, concentrate it to a single point of intensity, the way a magnifying glass concentrates sunlight to a single incendiary point?”
The UK is currently far ahead of countries like the US and China.
The UK doesn’t get enough credit for its pioneering work in offshore wind power. They have helped push forward the industry and everybody else will benefit from these advances, in the same way that Germany helped turbocharge the solar industry over the past decade and now everybody benefits from cheaper solar power.
The final update of the Global Wind Energy Council (GWEC) of 2012 global wind power installation numbers has recently been published. Now Clean Technica has updated the “Top Wind Power Countries” lists. They are all about looking at relative rankings (or creating them when they don’t yet exist). That simply tells us much more about who the true clean energy leaders are than looking at total installation numbers.
Large batteries could be used for storing excess power from the electrical grid for future use.
New Stanford University research could point the way to large-scale, long-lasting power grid batteries. These kinds of batteries would be especially useful for making technologies like solar and wind power more practical, allowing vast amounts of storage to be stored for periods of time in which the skies are calm or overcast.
