A new law provides flexibility in terms of how the state can meet this new target for the electricity it consumes.
Most garages can double as EV charging stations.
As EVs make more inroads, giving tenants somewhere to plug in their cars could become a selling point.
Transportation is the biggest contributor to greenhouse gases by sector. Converting the U.S. fleet to cleaner electric vehicles would likely take decades.

What if the world really got serious about meeting global climate goals? Doing the math on current emissions and the pace of energy transitions shows how quickly fossil fuels need to be phased out.
You may agree the U.S. should move to renewables, but how quickly can we do it and how?
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.
Many bitcoins equals a heavy environmental burden.
The digital world is taking more and more space in our lives... and dramatically increasing electrical use. It’s a serious problem given the urgent need fight climate change.
Wind turbines require massive structures that are polluting to produce and can harm ecosystems, but these impacts compare favorably with those of fossil alternatives.
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.
Domestic energy production, both fossil fuels and renewables, has surged in the past decade, yet policy priorities haven’t.
Presidential candidates need to talk more about energy and address a tough question: what does the government do well on energy policy and what it should stay out of?
Despite worries over the lower driving range of electric cars, most trips can be done with existing electric vehicles.
Electric vehicles could cover the daily energy needs of nearly 90 percent of personal cars in the U.S., analysis shows
The Diablo Canyon nuclear power plant in California is closing and the state has committed to replacing it with greenhouse-free sources of electricity.
Can nuclear power plants like California Diablo Canyon be replaced without greatly raising emissions? It's an open question.
We need a global target for reducing emissions in agriculture to meet the Paris Agreement. Farmers have an opportunity to help meet the 2 degree C target in the Paris Agreement, but known practices will not be enough.
To meet global climate change targets, agriculture needs an array of innovations and money to get farmers around the world to adopt new practices.
Despite the benefits of going renewable, it may be harder to get there than we thought.

Phasing out fossils fuels would go a long way to stopping dangerous climate change – but it might be harder than we thought.
Low-carbon initiatives in cities like Rwanda’s Kigali can help citizens to deal with the harsh effects of climate change.
From an economic point of view, low-carbon plans in rapidly urbanising areas can have massive benefits for East African cities.
Americans like big vehicles – a serious challenge to reducing emissions.
American consumers just aren't prioritizing fuel efficiency in a time of low gasoline prices. Is there a way to reverse the trend and make progress on climate change?
South Africa has made promises to decarbonise but is hugely reliable on coal - so this is difficult.
The process of decarbonisation is a complex one for South Africa, as most its power supply comes from coal.
The U.S. oil industry is in the doldrums, but there’s not much the next (or current) president can do about it.
The next president will have little power to slow the growth of renewable energy, sliding oil prices or coal's decline.
If the U.S. moved to electric vehicles, there would be a substantial cut in air pollution – and health benefits to go with it.
Global warming is often seen as a problem for future generations, but focusing on the immediate – and substantial – health benefits of clean energy can change public perception of climate change.
The U.S. could dramatically increase solar and wind power without expensive energy storage. The key is to overlay high-voltage direct current power lines on our system of regional grids.

Developing countries need technical and financial aid to begin the transition to low-carbon energy now, not just pledges to invest in energy R&D with payoffs decades from now.
‘Decarbonizing’ the energy system is above all an infrastructure problem.
Dealing with climate change will require countries to 'decarbonize' their energy infrastructure. The history of infrastructure suggests this could happen quickly once the transition starts.
Rooftop solar panels: will they kill power companies or can they help them?
Many utilities see rooftop solar as a threat, but solar power can actually lower the cost of power they – and their consumers – need to pay during hours of high demand.
