The hydrogen economy is much nearer than we think
Hydrogen produced from renewable energy is already finding a market as a 'green' fuel for cars. But its future potential goes way beyond that, as a vital storage mechanism for surplus wind / solar electricity on the grid, to provide power on demand.

The future of solar power in 7 promising charts
Global growth of solar power and curbing climate change go hand in hand. If growth slows down, climate change will further its grip on the earth. Luckily, the expansion of solar power is going remarkably well thanks to plummeting costs of electricity. The Lawrence Berkeley National Laboratory Read More...
Fleet of self-driving taxis hits the roads of Singapore
Self-driving vehicles aren’t quite ready for full-scale rollout just yet, but in one part of Singapore, autonomous taxis will be giving people rides around town for free. The company behind this trial is nuTonomy, which has been testing its technology in Singapore without passengers for some time Read More...
The electric bus is coming to a city near you
The average transit bus travels about 130 miles a day. An electric bus from the company Proterra can drive 146 miles, on one electric charge. As battery prices continue to fall and state mandates to cut pollution become more pressing, many cities around the U.S are starting to replace their Read More...
Investing in off-grid renewables in the developing world: what you need to know
At the Paris climate talks last December, governments agreed to work towards limiting global warming to 1.5C above pre-industrial levels. But the topic of financing developing countries to help them adapt to climate change and transition to clean energy became a sticking point during the Read More...
Apple becomes a green energy supplier, with itself as customer
Although much of Apple’s manufacturing is done offshore, it still has extensive needs for electric power in the United States — and not only for the sprawling new corporate campus it is building at its headquarters in Cupertino, Calif., and its 270 retail stores around the country. One Read More...
These "trees" can turn wind into energy
A nice cool breeze in the summer would feel even better if the trees surrounding your yard were also generating electricity for your home. We’re used to the idea of capturing sunlight for energy, but now it’s also possible to capture wind energy through “wind trees.” Developed by a French Read More...
Scientists find way to produce plastic using much less energy
As much as we would love to rid the planet of plastic, the truth is we rely on it for everything from food packaging to smartphones. Besides plastic pollution, the process of making plastic is also expensive and strenuous on the earth. Scientists claim that may all change soon with their Read More...
Tesla's Elon Musk says new car battery is a milestone
Tesla Motors has unveiled a new battery pack for the performance versions of its Model S and X cars that will extend the range and mean faster acceleration. Elon Musk, chief executive of the electric car maker, hailed the upgraded battery as a "profound milestone". He said the battery cell Read More...
Aussie scientists set solar efficiency record
Scientists from the land down under have set a world record in efficiency for a solar thermal dish generating steam used to create electricity. The Australian scientists redesigned their concentrating solar thermal system and found that 97% of sunlight was converted into steam. It’s the best Read More...
