The fossil fuel era won't last forever. And a new set of countries will find their reserves of lithium, copper and rare earth metals are in high demand.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Many Puerto Ricans are happy to see their broke power utility sold off to whoever can get the lights turned back on. But privatizing the island's energy grid may bring more problems than relief.
February is the riskiest time of the year for blackouts, as the nation returns to work and school and soaring temperatures put pressure on the system.
Raising the cost of solar panels coming to the US could rekindle interest in a simple but potentially significant technology: solar reflectors.
Slapping duties on imported panels is unwise.
Diatoms' tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney's backyard add up to a zero-carbon energy solution for the city.
Tesla, China and Richard Branson are among those offering to help Caribbean nations rebuild – and do so in a greener, more resilient way – after the devastating 2017 hurricane season.
Yes, Puerto Rico and any other storm-vulnerable location could benefit from on-site solar and battery backup, but it's unrealistic to say these microgrids are enough to power the island.
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 news that solar power capacity will outstrip nuclear by 2018, what do those assertions really mean?
A trade spat could jack up the cost of going solar, killing jobs and obstructing efforts to do something about climate change.
On Q&A, an audience member said renewable energy is 'now cheaper than coal'. Senator Matt Canavan disagreed, saying renewables are not 'at the moment, cheaper than coal'. Let's look at the numbers.
Solar PV and wind energy have overtaken coal as the leading sources of new electricity generation worldwide, with falling prices and new storage technologies making clean energy ever more attainable.
The UK is about to miss an opportunity if it tries to take on the giants of the lithium-ion battery industry.
How fast can the US transition to clean energy and with what energy sources? Here's why an impassioned debate among energy wonks matters to the rest of us.
India, the world's fourth-largest carbon emitter, long resisted calls to fight climate change. Now it is investing heavily in clean energy and expects to meet its Paris climate accord target early.
Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Africa's energy potential remains under-exploited, the energy entrepreneur is well-positioned to take advantage of the opportunities presented by the energy sector.
