Energy sources and energy crisis |
|
The energy sources are divided into three categories: fossil fuels, renewable sources, and nuclear sources. The fossil fuels are coal, petroleum, and natural gas. Renewable energy sources are: solar, wind, hydroelectric, biomass, and geothermal power. The nuclear-powered sources are: fission and fusion. Energy crisis situation that scientists predict will occur sometime in the 21st century. As man continues to deplete the world's natural reserves, alternatives to known energy must be discovered. World leading scientists have now analyzed these pressing concerns and concluded that the energy crisis poses one of the greatest threats facing humanity this century.One of the recommendations is that biomass based renewable fuels and energy hold great promise for addressing climate-change and energy-security concerns. Bio fuels is derived from biomass such as waste from organic material ( sawdust, rice husk e.t.c. ). Unlike other fossil fuels such as coal and gas, biomass is a renewable energy source. Like some fossil fuels, biomass is a form of stored solar energy. The energy of the sun is captured through the process of photosynthesis in growing plants. Crops specifically grown for use as bio fuels are produced all over the world. Biomass may also include biodegradable wastes that can be burnt as fuel. Although fossil fuels have their origin in biomass, they are not considered biomass by the generally accepted definition because they contain carbon. Fossil fuels are not renewable, whereas biomass is renewable energy source, because the growth of plants replenishes the supply. People must learn to slowly detach themselves on being too dependent on the use of energy sources that are non-renewable and expand on the use of renewable energy, green energy sources and bio fuels.
