California, where I live passed a law that the electric grid be
powered by 100% renewable energy. Some said it was a dream but
economic forces are already such that the plan is ahead of schedule.
Last year for a few days the grid over 50% renewable
You get about 17 megawatt hours ($2800 at my current rate) from one
$400 panel before the 20 year warranty expires. That is a 30% rate
of return on the initial investment. Itis no wonder that Telsa is
offering to place panels on your roof for free, but they retain
ownership of the panels. They just want your roof. A 30% return on
investment look good to them.
THere is also a law requiring panels of every new home. With a law
making everyone by pannels and a company in effect offring to give to
away free the market will "explode".
Can fusion compete economically. It's hard with the competitor is free solar.
What to invest in? Easy energy storage. With nearly free daytime
power and expensive night time power the idea is to buy power inthe
daytime and sell it at night. Local utilities doths, we have a few
reservoirs where the power company pumps water up hill when the cost
of power is low and then runs the water to a lower reservoir and sells
the hydro-power when the cost is high. Re-use the water a few times.
Tesla is sells every battery they can build both to end users and
power utility companies. They make LiPo battery banks as large as
shipping containers. The economic incentive is "insane" The "buy
low sell high" cycle is very predictable and you make a 50% per day
profit on buying and selling power based on time of use.
Fusion will be expensive and solar is already making people a ton of
money. There will be a use for fusion power but it is at least 50
years away and by then most of the world will be on renewable power.
But yes, there will always be a need for baseload especially as cars
go electric after the bans on gas cars take effect. The
electricication of the entire transport system will keep the demand
side going.
