1. Introduction
The worlds electricity generation is about 17, 450 Twh. The most of which comes from coal and 20% of which comes from gas, and 16% of which comes from nuclear and hydro each. The coal is the carbon di oxide emitting substance per Kwh. The other pollutants are at the high levels. This substance continues to dominate the market with low cost and high availability. This substance continues to dominate the market with low cost and the high availability. This affects are not going to reduce the emission amount. The future investment is always needed to save the environment and the energy. The indicators are based on the environment and the social impacts. The research has already given to know the importance of the economy of electrical generation. Life cycle analysis is the important tool for the analysis the electricity.
2. The Renewable Energy Technology
The price of the electricity generation using the renewable energy resources is usually low. The price of the electrical generation using the coal or the gas is very low. The electrical power generation such as wind and the PV analysis acts as the backup sources for the power generation. PV has a widest range in electricity generation in the large way. The long distance in the transmission lines are very common in the case of renewable energy resources. The non combustion energy resources show the high capital intensity with the zero fuel emission rates. The renewable energy resources are considered as one of the dominant energy resources with the high amount of electrical power. This is considering as future energy resources for power generation.
3. Greenhouse Effects
The green house effect has much more amount of CO2 rate, which have high capacity to increase the earth’s temperature. The hydro and photo voltaic have very low rate of emission rate of emission. The average emission rate of geo thermal is used together. This range includes all the gas emission. In both Pv and wind power, the most of the emission comes from electricity. The average grid mix is used to calculate the emission rate. The hydro power, biomass has very low emission rate. The dam construction has much more impacts on CO2 emission. The tropical renewable energy resources have the highest emission rate. The geothermal resources have the significant impact on the energy losses. The waste energy has 90% of the emission rate by weights. This geothermal power has the large amount of energy. This type of water consumption rate has the reinjection of the polluted resources. This type of cycle has low life cycle water consumption. This renewable energy resource has both positive and the negative impact on the energy generation is the independent from the fossil fuel impacts. This solar cell offers very good source of electricity without the fuel dependence. This solar cell requires large amount of electrical power.
4. Conclusion
This technology has the selected sustainability indicator. This technology was ranked from 1 to 4 with the corresponding indicator. The values of the energy were quantifiable. The average range of energy was considered together. The geothermal energy is slightly limited worldwide. The solar energy is considered as the most limited energy resources. Most of the countries are adopting the renewable energy resources, like Saudi Arabia, etc. this energy is going to be the future energy resources.
