How to have an all-renewable electric grid

We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
Expanding solar power potential more than it’s needed could replace more expensive energy storage. Jamey Stillings

A radical idea to get a high-renewable electric grid: Build way more solar and wind than needed

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.

Spread of self-driving cars could cause more pollution – unless the electric grid transforms radically

The spread of ride-hailing services and autonomous vehicles will lead to higher energy demand, a study finds. Electric vehicles and a much cleaner grid are the only way to avoid more emissions.

Why doesn’t the U.S. bury its power lines?

Hurricanes Michael and Florence have knocked power out for millions of people. Burying power lines could help but the costs are high.
The latest research suggests that in Australia, rooftop solar photovoltaics are more likely to be adopted by middle-class households.

Are solar panels a middle-class purchase? This survey says yes

Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.
Grid operators set the prices for energy markets and are structured to take the lowest prices – a disadvantage for coal and nuclear power.

The pull of energy markets – and legal challenges – will blunt plans to roll back EPA carbon rules

Two moves by the Trump administration signal a dramatic shift in energy policy to favor coal and nuclear, but markets forces and legal challenges mean changes could take years.

Renewables will be cheaper than coal in the future. Here are the numbers

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.

Conflicting laws keep Nigeria’s electricity supply unreliable

The centralised regulation of electric power in Nigeria is stalling progress in the sector. To achieve stable power supply, the country must obey its constitution and decentralise regulation.

‘Energy Brexit’: What are the consequences on both sides of the Channel?

A year after Brexit, experts from the Grenoble École de Management and the Centre for European Economic Research look at what impacts the UK's leaving the EU could have on energy prices and security.
