No. Production of solar panels and electric cars pollute and emits CO2. Buying solar panels means producing pollution.

The best way to save the environment is to buy overpriced, locally produced vegetables, so that you cannot afford to buy a car.

One of the most environmentally friendly cars is to drive a WW2 jeep. Because it's old.

CO2 reduction is not something you buy. It's something you don't buy.

>>It's just amazing to me that there are not more residential solar companies trying to take advantage of this opportunity.

The payback for solar installation without rebate is something like 30 years, and as the current generation of solar cells degrades 1% or so per year, still not practical without substantial rebate.

That being said, customers of xcel energy in Colorado can get over 1/2 the cost paid for by rebate.

I wish I was on their system.

However $25 or 30k investment, without significant payback means still not a practical use of funds.

How much oil does it take to manufacture a solar panel? And in the lifetime of the solar panel, is the energy produced less than or greater than the energy it took to create the panel?

If the energy produced is less than the energy to manufacture, then you've actually increased your carbon footprint.

How many panels would the average person need to power a car and all their home needs, say, in Southern California? How about western Oregon? I'm just guessing here based on things I've read in the past five years, but I'd say for San Diego, the cost would be about $40,000, and in western Oregon, about $80,000.

The answer as to whether or not this lessens or increase eventual carbon output is unknown to me.
