use renewable sources of energy

Answer 2

Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energymore efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less).
By reducing emissions, energy conservation helps to prevent climate change. Energy conservation makes it easier to replace non-renewable resources with renewable energy. Energy conservation is often the most economical solution to energy shortages.
