Solar and wind can’t deliver power on demand. But overbuilding solar and wind, and simply dumping unneeded energy, would go a long way to smoothing out those bumps, study finds.
The Trump administration’s Affordable Clean Energy Plan would help the declining coal industry, but a study shows many coal workers could transition to a new industry – solar – and earn more money.
Blockchains and AI could play a key role in the decentralised energy systems of the future.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
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.
South Africa’s power utility would do well to consider swapping out expensive new coal-powered capability for renewables.
Innovation in small-scale solar systems and mobile money systems is giving people in sub-Saharan Africa access to electricity at a lower cost than diesel or kerosene.
Lowering your carbon footprint by living off-grid is a sustainability dream. But how possible is it using current technology?
A massive rural on-grid electrification programme in Rwanda has delivered considerable benefits. But is it the most sensible way to deliver power to remote areas?
The European Investment Bank’s funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
New modelling suggests that Australia could use renewable energy to hit its 2030 emissions reduction targets, without it costing any more overall than maintaining the status quo.
Amid news that solar power capacity will outstrip nuclear by 2018, what do those assertions really mean?
If you’ve ever wondered why you can look at a solar eclipse and why it can harm your eyes, the answer is in the sun’s rays.
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.
If harnessed properly, the sun holds tremendous potential to provide sustainable energy for the earth.
New research shows it only takes a few countries to kick-start the kind of global transformation required to meet the Paris Agreement’s long-term goals.
Massive new coal plants planned for Pakistan will further harm the environment in a country already suffering the effects of climate change. Solar energy is a clear alternative.
Relying less on fossil fuels is one of the key challenges of energy transition, and taking weather variations into account can help increase the overall efficiency of a renewable-energy system.
No energy source is perfect, but solar and wind have a much lower health and environmental footprint than fossil fuels, a study finds. Biopower, though, is a mixed bag.
