Millions of solar panels clustered together to form an island could convert carbon dioxide in seawater into methanol, which can fuel airplanes and trucks, according to new research.

These homes could dramatically reduce the cost of solar energy for homeowners.

The university, which is as big as a city, has slashed its carbon emissions since 2004. That effort is now paying for itself in lower energy costs. Could actual cities do the same?

The UK’s next wave of offshore windfarms will generate clean electricity at no extra cost to consumers after record low-subsidy deals fell below the market price for the first time. New offshore wind projects will power millions of British homes under “zero-subsidy” support contracts within the next four years, following a record-breaking government subsidy auction.

The world's largest furniture manufacturer is going off grid.

Germany and Slovakia have committed to phasing out coal. The two European nations are the newest members of the Powering Past Coal Alliance.

Ahead of the UN climate summit and the global climate strike, the world's largest search engine announced that the tech behemoth will make its biggest corporate purchase of renewable energy yet, signing on to a series of agreements that will increase Google's wind and solar investments by 40 percent, as Quartz reported.

The world's largest offshore wind farm is taking shape off the east coast of Britain, a landmark project that demonstrates one way to combat climate change at scale. Located 120 kilometers (75 miles) off England's Yorkshire coast, Hornsea One will produce enough energy to supply 1 million UK homes with clean electricity when it is completed in 2020.

It’s the latest “Powerhouse,” a name the architects at Snøhetta invented to describe super-efficient buildings that generate power for the community around them.

Solar power continues to set stunning new milestones in the renewable state of South Australia, reaching 80 per cent of total demand on Saturday and accounting for more than 70 per cent of demand over four hours in the middle of the day.

California's Tehachapi Pass is already home to one of the largest wind farms in the world, and now Amazon is coming, building a huge wind project in the area. How renewable-energy projects from tech giants are changing life in small-town America.

Our dependence on fossil fuels has remained about the same for 30 years.

Our planet Earth has an abundance of fuels such as coal, petroleum, which sadly is diminishing at an alarming rate .

Solar power may currently make up less than 2% of the world’s energy mix, but the outlook of solar company executives is, uh, sunny. “What’s important is new [energy] generation, and in the US, renewables are 70% of new generation. It’s game over,” said Tom Werner, CEO of SunPower, the California-based solar company, speaking at the Fortune Global Sustainability Forum on Thursday in Yunnan, China.

A new thermoelectric generator could bring light to one billion people who live without power...if market forces will let it.

Natural gas is a behemoth in Pennsylvania in terms of production, consumption, and electricity generation. According to the U.S. Energy Information Administration, natural gas is the top form of energy consumption in the state, and about 40 percent of electricity in Pennsylvania is generated from natural gas, just behind nuclear energy. Nationwide, natural gas is the single largest share of electricity production.

HONG KONG — The busy rush hour in Shenzhen, a new city of some 20 million people in Guangdong Province, is almost silent. Commuters whisper past on electric bikes and scooters or board one of Shenzhen’s fleet of electric buses and taxis, all part of the city’s pool of 90,000 new energy-efficient vehicles. It’s part of what Chinese city officials call “ecological civilization.”

As the world reaches for cleaner energy, hydrogen has long been viewed with a lot of hope. Often called the fuel of the future, the gas can be used to generate electricity and power vehicles. It produces water — not carbon — when burned.

Europe is home to some of the world's most ambitious and innovative wind energy projects.

Rare earth metals are used in solar panels and wind turbines—as well as electric cars and consumer electronics. We don't recycle them, and there's not enough to meet growing demand.
