PV Gap

Shannon Said:

Do large arrays of solar cells reduce global warming?

We Answered:

Solar photovoltaic cells are much more expensive than wind turbines as a means to produce electricity.

The cost of electricity produced by wind turbines is approximately 4 cents per kilowatt hour(1)

That is less than the cost of production of electricity by the use of Natural Gas and only slightly more than the cost of production of electricity when Coal is used as the fuel.

The best way to stop Global Warming is to stop the use of fossil fuels for electricity production.

The best way to encourage people to use electricity that is generated without the production of Carbon Dioxide is to make certain that the cost of production of the electricity is not significantly higher than the cost of production of electricity produced by fossil fuels.

The only source of electricity that does not produce Carbon Dioxide or other toxic waste and has a cost of production close to the cost of electricity produced by fossil fuels is electricity produced by wind power.

The cost of production of electricity by the use of solar photovoltaic cells is approximately 10 times higher.
