Out with the coal, in with the geothermal: New Zealand shifts to clean energy
Historically, New Zealand has relied on coal as its main fuel for development. No more.The country's share of renewable electricity generation, already the fourth largest in the world, is now close to 80 percent. With the quick rise in geothermal generation, New Zeland is well on its way to Read More...
New Aqueous Lithium-Iodine Solar Flow Battery Promises Energy Savings
A new system combining lithium-iodine batteries and solar cells — an aqueous lithium−iodine solar flow battery — has been created by researchers at Ohio State University. The new battery system promises energy savings of nearly 20% as compared to conventional lithium-iodine Read More...
The innovators: cheaper batteries could help electric cars hit the mainstream
There was a surge in the sale of electric cars last year but the number leaving the forecourts is still dwarfed by traditional gas-guzzlers at a ratio of almost 50 to one. The high cost of the batteries that power the vehicles is a prime reason. Sheffield-based Faradion believes it has found a Read More...
Norway wants (nearly) all cars on its roads to be emissions-free by 2025
Norway has the world's highest per capita use and sale of electric cars. Its embrace of electric cars will continue as a member of parliament has now commented that the country is aiming for all new vehicles (or well, nearly all) to be completely emissions-free by the year 2025. All municipal Read More...
Undamming rivers with solar panels and free salmon
Hydroelectric power is listed as an important source of clean energy. But in reality the dams produce only modest amounts of power while causing enormous damage to rivers and fish populations. Two Yale professors propose to take down the aging dams; restore the natural ecology of the rivers; build Read More...
Is the Caribbean a paradise for renewable energy?
Derek’s one-door shop selling cakes, sweets and soft drinks in Barbados appears at first glance to be just like any other, until you lift your eyes upward. On the roof is an array of solar panels arranged in a less-than textbook design, but the aesthetics don’t matter. What’s Read More...

This solar panel coating boosts the efficiency of a solar panel by using infrared
Every time the sun shines on a solar panel, it sends a portion of infrared energy along. But up until now, solar panels did not know how to handle that infrared light. But researchers at the University of California Riverside recently discovered a coating for solar panels that allows them to use Read More...
Climate change dream scenario: A power plant with negative emissions
The giant coal power station at Drax in Yorkshire in the United Kingdom, with its 12 cooling towers, is one of the world’s largest greenhouse gas emitters. It sends some 23 million tonnes of carbon dioxide up its stacks each year while supplying up to a tenth of the UK’s power. But that Read More...
