And it’s here where the rubber meets the street. Those yearly averages are nothing but one method to shift costs renewables should be bearing over to the fossil generation assets. A truly honest company would only state their energy that actually came from renewable assets as their renewable share. Buying fossil power over nighttime and selling excess solar power during daytime at a guaranteed price (above market) just shots excess power into the grid when it’s not needed pushing power prices down for the others. We need a database of all those companies that signal virtue with this fraud and cut their possibility of getting fossil power during night or at least don’t guarantee fixed prices for their unneeded solar daypower. Right now, they make power more expensive for the average user which shifts the cost of renewable power en more towards those that can least afford it.
While 160 companies around the world have committed to use “100 percent renewable energy,” that does not mean “100 percent carbon-free energy.” The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study published in Joule.
