Sure, but there is an awful lot that is learned by trial and error. The democrats, who will never admit they are wrong about anything, are really risking destabilizing the economy with their Monkey See, Monkey Do approaches to carbon. For instance, peer-reviewed studies show that biomass is not only not carbon-neutral, it can be worse than burning fossil fuels

and the much touted Germans are not going to come close to reaching their goals in the time frame allowed. They also are putting their energy supply at risk ( "But McKinsey issues its strongest warning when it comes to Germany's increasingly insecure energy supply due to its heavy reliance on intermittent solar and wind. For three days in June 2019, the electricity grid came close to black-outs.
"Only short-term imports from neighboring countries were able to stabilize the grid," the consultancy notes.
As a result of Germany's energy supply shortage, the highest observed cost of short-term "balancing energy" skyrocketed from €64 in 2017 to €37,856 in 2019.
"It can be assumed that security of supply will continue to worsen in the future," says McKinsey.
Renewables are causing similarly high price shocks in other parts of the world including Texas, Australia, and California.
And Britain and Australia have faced similar energy supply problems in recent years as they have attempted to transition to intermittent renewables.
“Wind generation, solar and interconnectors are different to the conventional electricity generation sources,” Britain's National Grid said in a report after lightning knocked a wind farm and natural gas plant off the grid in August, causing a black-out in London.

Nuclear is carbon neutral at the production level and offers stable, reliable and less expensive energy.
