Small-scale renewable energy projects can power rural areas not connected to the main grid. But investors may hesitate if future electrification remains unpredictable.
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
Energy experts are getting excited about a proposed solar farm in Kent and what it could mean for a clean energy future.
Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
Our energy system puts consumers more or less at the mercy of business and regulators. What if the future of energy meant putting the power back in the hands of households?
What's at stake as the Trump administration imposes trade sanctions on imported solar panels? A look at the US solar energy industry, which generates more than twice as many jobs as coal energy.
The price of renewable energy will fall significantly relative to new-build coal in coming decades, making an all-renewable electricity system more desirable, both economically and environmentally.
Amid the gloom, here are some hopeful signs that we can meet our climate obligations.
Photovoltaics and wind energy now have such a large head start that no other low-emission generation technology has a reasonable prospect of catching them.
South Africa his rich in minerals that, combined with the development of nanotechnology, can be used to help it develop new energy technologies.
Electric utilities want to quash distributed solar because they don't want the competition, right? Perhaps, but if you rely at all on the grid, you have a stake in this fight, too.
