Rank best energy sources?

Question

rank best energy sources

I hear it costs a lot of energy to create solar panels or bio fuel.

Crazy people say hydroelectric dams kill fish.

So what are the best sources or energy.

1 Hydro-electric dams.

2 Geo-thermal

3 nuclear

etc..

Answer 1

Why would you word it as "crazy people" say? Do you own a dam ? Do you even know what a Salmon is?

Hydro-electric dams are very efficient, but take many years to build and take tremendous amounts of energy and concrete (which is very expensive anymore) to build. Also they silt up.

Geo-thermal has a high cost up front, but pays off in the long run, but only heats or cools your space to about 58 degrees.

Nuclear is very similar to hydro with initial start up cost but then you need to deal with the waste.

Not sure where you got your info about bio-fuels because that is something you can make in your own garage with scraps. You must have meant ethanol and you are correct in that, if we continue down that path we will be worse off.

Lastly solar panels need to be looked at like compact florescent bulbs, they cost more up front but pay you back over time. In Colorado on average spending about 9k for an on grid solar panel system gets you a net metering and a check cut back to you at the end of the year for about 300 dollars.  Also other forms of solar energy such as wind and passive and hot water are very cheap and pay for themselves right away.
