No. Unfortunately, Democrats and Republicans both play useful idiots in the pro-Establishment fight against innovative anything and especially against clean energy. We've seen that over and over.
Every single political move by Democrats in California has actually impeded clean energy and promoted dirty energy. They just know how to lie lie lie. Democrats were front and center in complicitness in killing the electric car in the 1980s, 1990s, and 2000s.
Elon Musk's most brilliant value is calling all their damned bluffs. Quixotically, they have little choice, just running around trying to save what's left of their houses of cards. The best thing is improvement for the future, and Elon could bestow upon them forgiveness for their sins due to the directionality of that improvement of the future.
The way I think you mean "impeachment" (Trump's removal from office and the success of Communism taking over the world), Communists do not care about clean energy. They would slow down innovation. The fastest way to fix problems is through a sensible free market (light regulation in the right places).
(For the ignorant: Impeachment means a great trial where the Senate gets to put a lot of Democrat-supporters in jail, and Trump will be wildly vindicated, and furthermore, his supporters will be very motivated to vote for him. His removal from office would similarly compel our country to be even more strong against Communism. The dirty status quo is being fought most by Trump and the pro-Trumpers, however, many of them remain useful idiots against innovation. Furthermore, everything is very confused by issues of scope: nearby, we need coal, and far out, we will only have solar. 2030 is a fake deadline invented by Communists attempting to steal power and money, not clean energy. The boats shipping Chinese products to USA pollute more than every car and truck in existence. Now recalculate who really cares about conservation of humans and the environment and stopping pollution. Elon Musk cares. Chairman Xi, Putin, and the Iran Mullahs do not.)
Huh? How is impeachment of a president linked to communism? Or is this supposed to be funny?
I see signs that a number of Republicans in the Senate are preparing to get rid of Trump. The Syria thing was the last straw for a number of them. Ultimately Republicans will do whatever they think will get them re-elected. If enough of the public is calling for Trump's removal, they will dump him like a hot potato.
There is a handful of people in the House who actually like Trump, but the Republicans in the Senate loath him and just kiss up to him to mollify his base. Mitt Romney can afford to be anti-Trump because Trump is not popular in Utah.
As for the original question about removal of Trump, renewables, and Tesla... Short term I doubt it will have any effect at all. It could contribute to a Democratic landslide next fall which will probably help green energy some. Probably not as much as the eco voters want, but Democrats are generally more positive about green energy than Republicans. As @Ulmo pointed out Democrats record on actual green energy policies misses the mark for quite a few eco voters, but their record is generally better than Republicans.
In the short term, the entire market would tank.
I doubt it. The economic types have been very nervous about Trump from the beginning. Trump had to go all the way to the bottom of the barrel to find an economic advisor who agreed with him (Peter Navaro). The rest of the economic world think Navaro is a nut job. The economy right now is weakening and Trump's trade policies are contributing. If Trump was out and Pence made moves to reverse Trump's more controversial moves like the tariffs, the market would likely surge on the news.
Short term markets are driven by emotion and the emotion on Trump's removal will be relief. Longer term markets are driven by what' going on in the world and there are things in motion (some caused by Trump, some not) that could send the markets down.
A major war in the Middle East is more probable now than it has been in decades, that could send oil prices skyrocketing and cause major damage to economies around the world. It would also likely get consumers thinking seriously about electric cars. High oil prices would hurt Tesla production, but would boost demand to heights never seen before.
The trade war with China is hurting both the US and China. The US is getting hurt more. There are exports from the US that may not recover for decades, if ever. The Chinese were buying a lot of food from the US, but they went elsewhere. The fires in the Amazon are in part because the Chinese are buying more ag products from Brazil and farmers are clearing more land to grow food for China. If the trade war ends, China isn't necessarily going to come back to American farmers and if they do they will want lower prices because the world market is bigger now.
Something happening completely separate from Trump is Brexit which could destabilize the EU and the UK. Nobody is sure what the impact of that will be. Economists in the UK have estimated that the result could range from moderate damage to the UK economy to complete collapse in a worse case scenario. Any major economic impacts on Europe will ripple throughout the world economies.
