Renewable energy replaced coal as Germany’s main power source for the first time last year, according to Reuters.
Renewable sources of energy accounted for 40 percent of German electricity production in 2018, up from 38.2 percent in 2017 and 19.1 percent in 2010.
Germany, the economic powerhouse of mainland Europe, aims to get 65 percent of its energy from renewables by 2030, abandon nuclear energy by 2022 and ultimately cease relying on coal, Reuters reported.

Renewable energy sources supplied nearly 65 percent of Germany’s electricity last week, with wind turbines alone responsible for 48.4 percent of power production nationwide, Clean Energy Wire reported. As a result, fossil fuel plants ran at a minimum output and nuclear facilities were shut down at night.
“These figures show that the envisaged goal [of the German government] of 65 percent renewables by 2030 is technically feasible,” Bruno Burger, a researcher with the solar research institute Fraunhofer ISE, said in a statement.

Germany, one of the world’s biggest consumers of coal, will shut down all 84 of its coal-fired power plants over the next 19 years to meet its international commitments in the fight against climate change, a government commission said Saturday.

There are a LOT of improvements we can do to Our Civilization, if we try. Pretending that problems don't exist, or deciding to not deal with our problems, will not help.

Trucks driven in the US pay a fee to use the US highways, that cover about 10% of the actual cost. There is quite a bit in general taxation, however.
Trucks pay road taxes, mostly on fuel, like everyone does which is part of the problem—politics prevents raising the required revenue to fully pay for roads. Then, politics steals some of the money to subsidize mass transit that can’t recover costs thru fares or to build bike paths, HOV lanes, etc.

At night Germany buys its power from France, which is nuclear power.

If there are 2 humans left they will eventually find a way to kill each other.

I would guess that over 90% of our politicians do not understand the extent of the subsidies that we are paying, either through taxes, or through deficit spending. And, many subsidies are made indirectly, such as money for the military that is used to allow commerce to operate. An example of this would be the costs the military incur to stop piracy at sea, or the massive expenditures to ensure oil keeps flowing from the Middle East...there are many, many examples, that most people never realize.

Switching from carbon fuels to renewable, is not easy, but it has to be done, if we want Our Civilization to continue to provide us with modern conveniences...

Right now mature (commercially viable) battery technology can get to around 200 W hours/KG. Theoretical chemical limit is about 1,000 Wh/KG.
Jet A is 12,000 Wh/KG...
There's no uncharted territory in molecular chemistry which is going to provide an order of magnitude+ improvement in specific energy. The answer is going too be biofuel.

The only true picture of carbon foot print is the global one., and even these numbers are off, because China is illegally dumping unreported amounts of Greenhouse gases into the atmosphere.

Ooops, turns out those plants are located across the state line in NV, and were built there by opportunist investors when CA would not allow construction of sufficient internal generation capacity. As powerful as CA state government is, they haven't quite gotten to where they can seize infrastructure in other states
2. Transmit surplus grid power from New England (in cooperation with new england liberal politicians, I mean they all held a press conference together to announce this). Turns out new england's generation and grid is sized for winter heating requirements, but it's under-utilized in summer since it's pretty cool up there. Also turns out you can't transmit grid power more than a few hundred miles... they fell short on that by about 2,000 miles. Apparently none of those pols had an engineer on staff, or thought to consult one
