But mark my words, right - wingers will start screaming about compensation when all those shiny new gas - fired power plants they're building are threatened with closure when we start thinking seriously about building a modern grid that can shuttle electricity instead of curtailing renewable generation in one area while simultaneously turning on fossils in another.

643 SecularA said,» when 100 percent of new electricity generation capacity added to the USA's electric grid is wind and solar.»

The so - called «e-dumper» is being built from a massive Komatsu dump truck that weighs 45 tons when empty and has tires as tall as a person, and although that might initially seem like a strange choice for electrification, its intended usage is expected to produce a net surplus of electricity rather than draw a huge amount of grid power.

If we should have luck here in Germany, and the EEG does not fail, it would mean that in 20 years we'd have a grid mostly powered by renewable energy, paid by the private households alone, that will produce cheap electricity for the industry at a time when oil, gas and coal will be much more expansive than today.

Now, some readers will think this is far - fetched, but I think that in the not - too - distant future the day will come when 100 percent of new electricity generation capacity added to the USA's electric grid is wind and solar.

This new development has led to debate around what the appropriate level of compensation should be for distributed solar generation fed to the grid and what distributed generation customers ought to pay to utilities for non-electricity services, such as grid maintenance, as well as for electricity when their distributed generation system is not producing power (e.g., when the sun isn't shining).
