1.6 Solar Energy Conversion

Solar energy can be converted into some other useful form of energy sources using different conversion technologies as in Table 1.4. The methods are photoelectric, photoelectric-photothermal, photothermal, photochemical, photocatalytic, and photo-electrochemical conversion.

Table 1.4 Energy conversion [11].

      1.6.1 Sources of Renewable and Non-Renewable Energy

      Renewable and non-renewable energy are of two types, in general, on the planet earth used by living organisms.

      Renewable energy sources: Renewable energy sources are defined as the energy achieved from natural sources that are continuously produced by themselves for a day-to-day activity usage in a periods of time. These energy systems comprise sun, ocean waves, biomass (wastage of vegetable materials), hydel-power plants, and also some other such resources. This type of energy is also stated as green or sustainable or nonconventional energy sources.

      Non-renewable energy sources: Non-renewable energy sources are defined as the fuel that do not rejuvenated itself continuously once utilized on the scale of levels that sustain its rate of consumption. These resources are presented in a larger amount of fixed quantities and used quickly as faster than nature could produce. Some best suitable instances are coal, nuclear energy, fossil fuels, natural gas, petroleum products, uranium, etc.

      1.6.2 Differentiate Between Renewable and Non-Renewable Energy Sources

The difference in renewable and non-renewable energy sources was explained in Table 1.5.
