Solve it:_______.
1. A breakthrough in one of these areas will hopefully provide a means of relieving both the overstretched oil market and the environment.
2. Researchers in the automobile industry are experimenting with different types of engines and fuels as alternatives to the conventional gasoline engines.
3. One new type of engine, which burns diesel oil instead of gasoline, has been available for several years.
4. Finally, several automobile manufacturers are experimenting with methanol, which is a mixture of gasoline and methyl alcohol, as an automobile fuel.
5. A further type is the gas turbine engine, which can use fuels made from gasoline, diesel oil, kerosene and other petroleum distillates.
6. The increasing depletion of oil reserves, along with environmental concerns, have prompted some radical developments in car design over the past few years.

Explanation:

All these efforts are geared towards obtaining green energy supply that will ensure clean and sustainable environment. Environment-friendly fuel will end environmental degradation, preserve the ozone layer, and ensure healthy atmosphere for man, and encourage biodiversity. Fossil fuel has endangered the environment since its discovery. We need to start reversing its degrading impact now.
