A warmer planet can support more life than a colder planet.the switch to renewable energy would happen on it's own purely due to technology advancements reducing costs while increasing performance.
where the difference is .. time for it to actually happen .. tax incentives accelerates the economics and makes it possible to bring a new technology to the marketplace.
look at the massive $$$ tax dollars already poured into say A123 which did a belly flop with tax payer funded technologies ending up with Chinese owners. vs Tesla has already made it's technologies freely available to anyone.
what makes it all work is Tesla delivering a world class product!!!
like it or not the world is changing ... we've just had the HOTTEST July in history with more coming .. with scary things happening like MASSIVE frozen methane deposits getting released by global warming. etc. etc.
screw worrying about why global warming is happening .. let's worry about consequences what's happening right now .. permafrost melting is releasing all sorts of nasties .. from releasing mega huge deposits of methane to large numbers frozen deer carcasses that died from Anthrax and is now spreading, etc. etc.
if that happens .. planting millions and millions of trees may be the only way to save our climate from possible massive changes. of course switching to renewable energy which Tesla cars are but a small part .. what more exciting is the solar shingles combined with home storage .. which of course fuels Tesla cars.
Elon Musk has quite the forward vision!
