Turning CO2 to stone
Earth has limits to the amount of carbon dioxide in its atmosphere before the environment as we know it starts to change. Too much CO2 absorbed by the oceans makes the water more acidic. Too much in the atmosphere warms the planet. With emissions from our carbon-based economies rising, scientists Read More...
Solar up, coal down: U.S. shakes up energy supply
Solar power capacity in the U.S. will have nearly tripled in size in less than three years by 2017, amid an energy shakeup that has seen natural gas solidify its position as the country’s chief source of electricity and coal power continue to fade, according to monthly data published by the Read More...
Wind power could supply 20% of the world's electricity needs by 2030
According to a new report, wind power could supply as much as 20 percent of the world’s total electricity by 2030 due to dropping prices and pledges to take climate action. China is set to quadruple wind power capacity, and more investments are being made around the world to expand wind capacity Read More...
Scientists turn carbon dioxide into ethanol, by mistake
Scientists have accidentally done something incredible. They have created a means of transforming carbon dioxide into a clean fuel called ethanol, by mistake. The ethanol produced was said to be pure, meaning there are minimum side reactions. If produced on a mass-scale, this ethanol could be used Read More...
More than 190 countries agree on deal to limit global warming from air conditioners
This past Saturday morning in Rwanda, a landmark deal was agreed upon that will limit emissions of key climate change-causing pollutants found in air conditions. The deal will phase down the use and production of hydrofluorocarbons, known as HFCs, for use in air conditioners. HFCs are thousands of Read More...
The rapid growth of clean power begins to reverse global warming trend
The renewable energy revolution that The Optimist Daily reports on every day, is beginning to have a real impact on global warming. During the first six months of the year, carbon dioxide emissions from America’s energy industry dropped to the lowest point since 1991, according to U.S. Energy Read More...
A huge carbon capture scheme is reviving hope for “clean coal”
The plant will harvest 90 percent of the carbon dioxide it produces. by Jamie Condliffe October 5, 2016 When it reopens later this year, the W.A. Parish Generating Station in Texas will be the largest coal power plant in the world with a retrofitted carbon-capture system. But the scheme is perhaps Read More...
The latest car from Peugeot runs on… air
More on car innovation: Compressed air doesn’t sound a likely fuel for cars. However, French automaker Peugeot is building a hybrid gasoline car that can store energy as compressed air. The air-hybrid car can achieve 81 miles per gallon while emitting just a fraction of the carbon dioxide per Read More...
Artificial photosynthesis
Daniel Nocera, the rock-star of artificial photosynthesis, and his colleagues at Harvard published a paper in June that shows a viable route to long-term energy storage. The Science article demonstrates how surplus power from solar PV can be converted into liquid fuels. The Read More...
Engineers in Iceland come up with solid way to get rid of CO2 pollution
High up in Iceland’s western volcanic zone, engineers are sequestering carbon dioxide pollution by turning it into rock. Known as the CarbFix project, the engineers dissolve CO2 in water and send it deep beneath the ground where it reacts with basalt rock to become calcite. The engineers claim 95 Read More...
