The Real Cost of Wind and Solar
The Real Cost of Wind and Solar By Norman Rogers The main problem with either wind or solar is that they generate electricity erratically, depending on the wind or sunshine. In contrast, a fossil-fuel plant can generate electricity predictably upon request. Blackouts are very expensive for society, so grid operators and designers go to a lot of trouble to make sure that blackouts are rare. The electrical grid should have spare capacity sufficient to meet the largest demand peaks even when some plants are out of commission. Plants in spinning reserve status stand by ready to take over if a plant trips (breaks down). Injecting erratic electricity into the grid means that other plants have to seesaw output to balance the ups and downs of wind or solar. Adding wind or solar to...
