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?

When it comes to eliminating greenhouse gas emissions from transport, the future is already here on small islands.

Even before the British billionaire invested US$1 billion in making the region 'climate-smart,' Jamaica, Barbados and Dominica were pioneering a renewable energy boom in the Caribbean.
This is what a 5-megawatt, lithium-ion energy storage system looks like.

Energy storage could prove an inexpensive way for power companies to handle heat waves and other times when consumers use more electricity than usual.
Areas with greater opposition to wind energy development may be more likely to experience negative impacts on property values.
Research has found that wind turbines decrease property values in Ontario, but only when the community is opposed to their presence.
Robins are a much loved Christmas icon, but wind turbines installed in their habitat are affecting their song, with worrying consequences.
Replacing wind turbines could significantly increase Britain's power output.

In order to address a warming planet over the medium and long-term, climate policy must be designed to be adaptable and indeed attractive to those across the political spectrum.

There are some good explanations for the mismatch between regional support for climate action and the areas where renewable energy is making the biggest inroads.

Generating less electricity with fossil fuels could help save lives.
Solar lowers prices and shifts when daily peak demand hours are.
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.
Mass. Gov. Charlie Baker signed a comprehensive energy law in 2016 that authorized the development of new offshore wind and hydroelectric projects.

Several states, including Massachusetts and Rhode Island, have developed ambitious renewable energy targets that hinge in large part on getting their power from turbines stationed in the water.
Annual water requirements of a PHES-supported 100% renewable electricity grid would be much less than the current fossil fuel system, because wind and PV do not require cooling water.
Wind turbines are becoming as American as haybales.
While wind energy is often perceived as controversial, that may be due to the tyranny and power of unrepresentative anecdotes.
