Does Driving An Electric Car Really Help The Environment?

Seeing as I have to plug an electric car into my house, and my house runs on energy from the local non-green powerplant, doesn’t my car’s need for electric actually cause an increase in demand on the powerplant’s energy production- causing them to produce more power (and pollution)?

If we all switched to electric cars, wouldn’t the burden of producing energy for them just switch from the individual owner to the local power plant- with an increase in pollution to follow?

what is the best energy source that we should invest in rather than burning coal?

green-house producing sources like coal, although we have centuries of coal reserves, will place our future at very high stakes in aiding in global warming.
What is the best alternative to energy production that will be abundant and sufficient enough to prevent global warming?

How will Green Energy Production effect Food Production?

I was asked to do a report for Science on this question.

I dont understand the "Green Energy Production" part of that question… if you can tell me what you think it means, and find a website that is answering this question in some way, it'd be a huge help.

Should oil companies only be eligible for any government money if they use it all on switching to green energy

Would this help steer things in the right direction without harming the economy or costing any jobs? They could use some of it on job retraining to switch from oil jobs to green energy jobs and some on research, some on devolopment, some on advertising and the rest on producing green energy for new demand and to replace dirty energy production which would HAVE to be phased out in order to prevent the damage to the climate from the green house gases they would emit if they weren't replaced.

Financing & cultural challenges to getting more green energy adoption?

I'm curious to hear what some of the financing & cultural challenges are to getting traditional energy companies to adopt green technologies? In particular, I know that many green energy sources require significant up-front investment today to capture the benefits of potentially grid-parity kwh production in the future.

How does financing work in the energy industry today around the world and is it possible that the way energy production is financed might hinder large investments?

Also, what some of the cultural challenges to green adoption? For example, are $/Watt and $/kwh even the right metrics to use when thinking about the economics of adopting green technologies?
