Developing alternative energy sources reduce your need for oil and coal, primarily.
The need for non-conventional machining begins with the need for alternative energy sources. Non-conventional machining requires the use of alternative energy sources including thermal energy or solar energy.
we need different sources of energy in order to survive for example without chemical energy we can't have food and in order to survive we need food.
Dependence on fossil fuels causes environmental damage.
Dependence on fossil fuels causes environmental damage.
world is facing energy crisis. and we are depending on few of many available energy resources that are expensive and are not environment friendly. on the other side energy demand is increasing day by day. so we use alternative sources of energy especially environment friendly sources( solar, wind. etc)
Mainly two reasons. (1) The fossil fuels will eventually be used up. (2) Fossil fuels cause pollution.
Alternative energy sources for cars are being explored because we are running out of petroleum. We need to explore alternative energy sources such as power for electric cars from renewable sources like solar and wind energy, as well as alternative fuels such as hydrogen and algae-based biofuels, before conventional petroleum-based fuels like gasoline and diesel run out. Solutions like these are more environmentally friendly, and in some cases cheaper and more efficient than common fuels like gas and diesel. - Oscar
well soler energy is energy from the sun and global warming is the warming of the globe and you need the sun for both....so...

No, most have been found, they just need to be made available to the public soon, it takes time to develop new things.
