Most new wind and solar projects will be cheaper than coal, report finds:
Almost two-thirds of wind and solar projects built globally last year will be able to generate cheaper electricity than even the world's cheapest new coal plants, according to a report from the International Renewable Energy Agency (Irena).
The agency found that the falling cost of new windfarms and solar panels meant 62% of new renewable energy projects could undercut the cost of up to 800 gigawatts (GW) worth of coal plants, or almost enough to supply the UK's electricity needs 10 times over.
Solar power costs fell by 16% last year, according to the report, while the cost of onshore wind dropped 13% and offshore wind by 9%.
In less than a decade the cost of large-scale solar power has fallen by more than 85% while onshore wind has fallen almost 56% and offshore wind has declined by almost 48%. Francesco La Camera, Irena's director general, said the agency's latest research proved the world was "far beyond the tipping point of coal".
He said: "Today renewables are the cheapest source of power. Renewables present countries tied to coal with an economically attractive phase-out agenda that ensures they meet growing energy demand, while saving costs, adding jobs, boosting growth and meeting climate ambition."

Another option for storing off peak excess energy without using batteries is to just push train cars filled with rocks uphill, same principle as pumping the water uphill but is more flexible in terms of where it can be set up. Sadly I don't have the link to the article I read handy.
Some other non-battery alternatives are flywheels and compressing air into underground salt domes. They all work with varying degrees of efficiency and each could be used in the environment best suited for it. We need to be looking at all of them.
