Reducing the cost of solar energy continues to be an important aspect in the PV industry. The fundamental goal of solar energy is to be economically viable with present sources of electricity.
Increasing levels of pollution and contamination in the environment is a cause for concern globally. For me, or any other individual, we are confined to the environment we find ourselves in.

The Fischer-Tropsch (FT) process, originally developed by Franz Fischer and Hans Tropsch in early 1920s, is a series of chemical reactions that involve the conversion of hydrogen and carbon monoxide into liquid hydrocarbons by using a catalyst.
A microbial fuel cell enables the conversion of chemical energy to electrical energy when microorganisms react by catalysis.
The concept of a solar sail seems to be right out of a science fiction novel. However, this could become a reality as soon as 2014, when a NASA research team; ‘In-Space Demonstration of a Mission-Capable Solar Sail’, plans to launch a solar sail and prove the feasibility and significance of this technology.

A wind turbine converts kinetic energy from wind into 'rotary mechanical energy' which is used for doing work. In sophisticated models, rotational energy is converted to electricity with the help of a generator.

Geothermal heat pumps are otherwise known as water-source, ground-source, earth-coupled or geoexchange heat pumps.
Thermoelectric generators, or Seebeck generators, are devices that directly convert heat into electricity through a process called the Seebeck effect or thermoelectric effect.

Feed in tariffs is a process implemented to encourage renewable energy technology investments. Also known as renewable energy payments and advanced renewable tariffs, they offer long-term contracts for those who generate renewable energy based on the cost of production involved in each of the technologies such as wind power, solar power and tidal power.
