Why have we not developed alternative energy in last 30 years??

first of all, oil companies have too much to lose when we get off our addiction to oil. They will only go kicking and screaming like a two yo.

The technology is there. We just need to develop it. Only exception is nuclear and fusion technology. Both are not practical.

Examples of why things have not progressed.

Let's see back in the '30s or was it earlier, oil companies and other automobile companies bought up the trolly system in Los Angeles and proceeded to dismantle it. They wanted to sell cars and oil. Not for people to commute on a mass transit system.

Who killed the electric car? also a movie by that name worth watching.

NiMH battery patents and rights were bought up by you guessed it, oil company. And they sat on it until it expired. This precluded the development of NiMH battery and for its use in EV. look up on history of NiMH battery. Chevron is still mucking with it.

I think solar cells are only relevant where there isn't much of wind. I think we should be looking at different aspect of renewable energy instead of just electricity. We could be using solar heat to heat our water and to heat our house. Saves lot of energy!! and its lot cheaper than solar cell to generate electricity.

yes its one of my hot button.
