What two technologies reduce dependence on fossil fuel generated electrical energy?

Answer 1

There are really a lot of technologies, both new and old, that more or less reduce dependence on fossil fuels. I'll just name two of the more promising types of technology that are currently in active use and development. Battery technology (electochemistry) is a very major way of reducing dependence on fossil fuels for energy. The main advantage of fossil fuels is that they can be carried and spent relatively quickly, a reason for why most engines use petroleum. With lightweight batteries, energy from other non-portable sources (wind, solar, etc.) can now be used efficiently in areas that were once exclusive to fossil fuels. This reduces overall dependence on fossil fuels by allowing other types of energy to partially replace it.

Nuclear power is another very effective way to reduce fossil fuel dependence. Solar and wind power sources are limited by high costs and a need for extremely large land areas that cannot reasonably supply the world's entire energy needs. With Nuclear power, the cost of energy in relation to the fuel costs are negligible (about 1 cent/kwh depending on the plant) so that the fees mostly pay for the construction and maintenance of the facility. Nuclear plants are safer, considering that many people die every year mining for fossil fuels and countless others are harmed by the pollution. Generation IV power stations are also designed to generate power from nuclear waste, potentially eliminating a major hindrance.

Answer 2

Renewable energy technologies like solar panels and wind turbines can reduce dependence on fossil fuel generated electrical energy by generating electricity from Natural Resources like sunlight and wind. Energy storage technologies such as batteries can also help store excess renewable energy for use when the sun isn't shining or the wind isn't blowing, thereby reducing the need for fossil fuels.
