This is a common question that is often asked as more fuel is burned to produce electricity and other forms of energy. However, either human beings forgot or ignored the fact that most of the substances we use for fuel is non-renewable and supplies can be in short supply. We have seen the result of fuel supplies running low resulting in increased prices for gas and petrol and an increase in other things that use fuel. So not only might the humans be heading towards a shortage of fuel, there is growing animosity towards the damage that the uses of the present fuels have caused on the environment.

Substitutes

Therefore, it is vital key policymakers to look for some substitute sources of energy before the supplies become too low. The suggestions for substitute sources could include wind power, solar power, hydropower, geothermal power, and tidal wave power. Even hydrogen gas has been used in the past to power spacecrafts and parts of cars.

Geothermal power refers to the natural heat energy produced inside the earth. This power can be harnessed to heat buildings and homes. The most common form of this geothermal energy is seen in a hot spring or a geyser. The force necessary to spray water out of the Earth is a great source and this form of heat production has been used in Iceland for at least 30 years.

Nuclear power is one substitute form of energy. The use of nuclear substances and the mixed reactions associated with building a reactor, is still prevalent many years after the disaster at Chernobyl, Russia. However, nuclear power is much greater than the energy obtained from other sources. Some of the European countries produce at least 50 percent of their nation’s energy by nuclear power.

Therefore, before situation becomes critical major countries should start looking at diversifying the way they produce power for their country.
