I'm pretty sure that the environmental cost of storage batteries is less than the environmental cost of obtaining, transporting, and burning oil, gas, and coal.I will not disagree that man kind is affecting climate but to what degree is debatable. The planet has been heating and cooling since it was formed., There is a natural cycle here that we can not change nor most likely modify.
To conserve resources is important and to seek out alternative sources of energy is noble and a good thing. But to think that solar or wind is going to do the job is just dreaming. The wind doesn't always blow at the right speeds and solar only works when there is day light. And what is the environmental costs of storage batteries.
There is always a trade off that needs to be factored into the equation,.
I disagree with you about the magnitude of man's effect on the climate, but I recognize that there are many people like you who are not going to be convinced by scientists, government agencies, or observed effects. Since conserving resources and developing alternative sources of energy is a good thing whether or not one "believes" in human-caused climate change, my hope is that we can use government to create incentives that encourage conservation and renewable energy. People and businesses that take advantage of those incentives will do better than those that don't, and progress will be made. Carbon cap and trade makes the most sense to me, but I'm sure there are other incentive structures that make sense.
