What is the cheapest alternative energy to implement and how does it compare to existing conventional energy?

Question

What are current energy prices of alternative and conventional techniques?

Answer 1

Wind is low priced to start with but can be a problem as on the hottest days it may not work. solar is great but not all days are sunny. PV costs more energy to install than most ever produce. Ethanol costs more to produce a gallon than the energy you can get out-it needs some help. Nuks would be a great way to make ethanol after steam generator. And nuks cost so much plus what do you do with the pollution? Now Can you ask a Q that we can A without asking more Q's? I am working on a new energy/fuel that is clean, cheep to produce, and may be the fuel you use in the future to drive your car.

Answer 2

Biomass is a cheap and effective way of creating energy because most of the material burnt is waste from agriculture of forestry.  These sources are also sustainable as long as the carbon burnt in the biomass is replanted and is therefore sequestered.  What goes up in smoke is them put back into the plants used to burn and make power.

Thes answers demonstrate the diversity of options that exist.  The problem is that governments are willing to subsidise dirty industry and power generation and not green or renewable alternatives

Answer 3

Existing alternative technology for personal use is still very expensive in up front installation costs,but the pay off ratio is getting better every day. On an environmental point of view,it's the way to go in slowing the future effects of global warming.  For that reason alone,if you can afford to ,do it.

Answer 4

Solar is the best, not the cheapest up front, but in the long run, always the best.  Long after your oil runs out, long after your coal mine is closed, long after your nukes stop glowing, solar will still be there.  Think about solar panels made 30 years ago still work just fine.  The only power plant you want near you is a renewable one.
