These tools and more can help make the transition from non-renewable to renewable and environmentally friendly energy. However, currently each of these energy forms is significantly more expensive than fossil fuels, which will lead to economic dislocations and hardship if they become the only power source for the future.

Solar power can be used directly for heating and producing electricity or indirectly via biomass, wind, ocean thermal, and hydroelectric power.
This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight.
These are also not strictly renewable energy resources but are very abundant in availability and are very low in pollution when utilized. Energy left over from the original accretion of the planet and augmented by heat from radioactive decay seeps out slowly everywhere, everyday.
Energy from tides, the oceans and hot hydrogen fusion are other forms that can be used to generate electricity. However, none of these is sufficiently developed or abundant enough to substitute for fossil fuels use. Energy from the gravititational field can be harnessed by tidal power; and the internal heat of the Earth can be tapped geothermally. Wind and hydroelectric power are the direct result of differential heating of the Earth’s surface which leads to air moving about (wind) and precipitation forming as the air is lifted.
Wind energy can be used to pump water or generate electricity, but requires extensive areal coverage to produce significant amounts of energy.
It is not strictly speaking renewable since all reservoirs eventually fill up and require very expensive excavation to become useful again. Hydrogen can be burned as a fuel, typically in a vehicle, with only water as the combustion product. In certain areas the geothermal gradient (increase in temperature with depth) is high enough to exploit to generate electricity. Each of these is discussed in some detail with the final result being that each suffers from one or another significant drawback and cannot be relied upon at this time to solve the upcoming energy crunch. These countries are not only accelerating RE installations but are also integrating RE into their existing infrastructure to reach a 100% RE mix.


Every one of these power sources (with the exception of hydroelectric) has low environmental costs, and combined have the potential to be important in avoiding a monumental crisis when the fossil fuel crunch hits. The range is from solar water heating with solar collectors or attic cooling with solar attic fans for domestic use to the complex technologies of direct conversion of sunlight to electrical energy using mirrors and boilers or photovoltaic cells. At this time, most of the available locations for hydroelectric dams are already used in the developed world. This process releases copious amounts of carbon dioxide gases into the atmosphere and is a major contributor to unhealthy air in many areas.
This possibility is limited to a few locations on Earth and many technical problems exist that limit its utility. These energy sources are often non-centralized, leading to greater consumer control and involvement. Some of the more modern forms of biomass energy are methane generation and production of alcohol for automobile fuel and fueling electric power plants.
Or the hydrogen can be used in fuel cells, which are similar to batteries, to power an electric motor.
Another form of geothermal energy is Earth energy, a result of the heat storage in the Earth’s surface.
Other renewable energies that do not depend on sunlight are geothermal energy, which is a result of radioactive decay in the crust combined with the original heat of accreting the Earth, and tidal energy, which is a conversion of gravitational energy.
Soil everywhere tends to stay at a relatively constant temperature, the yearly average, and can be used with heat pumps to heat a building in winter and cool a building in summer. Due to the need for energy to produce the initial hydrogen gas, the result is the relocation of pollution from the cities to the power plants. This form of energy can lessen the need for other power to maintain comfortable temperatures in buildings, but cannot be used to produce electricity. There are several promising methods to produce hydrogen, such as solar power, that may alter this picture drastically.
