Document Summary
Solar radiation is also used directly by human society and indirectly by harnessing the movement of wind and rivers as part of the hydrological cycle. To make energy production more efficient and to reduce the amounts of energy that are wasted during its use: give some examples of energy saving in both the developed and developing world. In many countries of the developing world, energy lost by burning fuelwood on open fires can be reduced by using closed stoves, which is also safer, while converting wood to charcoal is more energy-efficient still. In many developing countries, power plants that run on fossil fuels use 5 or 6 units of fuel to make one unit of electricity. In more developed countries, the ratio is about 3:1 but can reach 2:1 in combined-cycle gas turbines. Most have relative to the burning of fossil fuels. One such advantage is that most renewable energy equipment is small, allowing much faster construction than conventional technologies.
