"renewable energy sources can be used as baseload power (no coal or nuclear baseload need ever be built)"
Since you've posted it here dozens of times I don't need to remind everyone that you claim that solar and wind need no (none, zero) energy storage. That means that they will never be "baseload" power: an intermittent source can never be baseload power without multiples of excess capacity and massive energy storage.
Any person with google can look up the wind power maps and then the solar power maps for winter, spring, summer and autumn to see that there are times of the year when solar may be putting out bunches of power while wind is next to zero. The only solution to that is to have plenty of extra solar power and many times the amount of widely separated wind farms that also have the ability to store their energy when there is extra energy being produced.
Since the electricity supply must exactly match demand at all times, that means many more natural gas powered power plants if there is no energy storage for excess solar and wind energy.
This is what the UK is doing:
======================================================================
Announcing its plans at the official opening of its new £160m hydroelectric scheme at Glendoe in Scotland, SSE said it would seek guidance from the Scottish government on proposals to build a 300MW and 600MW pumped storage plant in the Great Glen.
The company said it was aiming to submit planning applications for the two developments in 2011. It added that both projects would require new dams to be built, but insisted the pumping and electricity generation infrastructure would be built underground, limiting the visual impact of the developments.
Pumped storage systems work using two reservoirs that are built at differing heights. During periods of peak demand, energy is generated by releasing water from the upper reservoir to drive turbines. The water is pumped back up to the upper reservoir from the lower reservoir during periods of low energy demand.
The last pumped hydro plant was built in the UK more than 30 years ago at Dinorwig in Wales, but interest in the technology has been revived in recent years as energy firms look for a carbon-free means of plugging any energy shortfalls that result from the intermittent nature of wind power. The approach also allows excess energy produced by wind farms during periods of high winds to be effectively stored, by using the resulting electricity to pump water from the lower to the upper reservoir.
