• The continuous increase in average temperature (which was triggered by excessive use of coal and oil) will lead to devastating effects on this planet such as increase in sea level, changes in monsoon which might disturb the ecosystem, poverty, etc.!• United Nations Climate Accord has decided to restrict the increase of average temperature by less than 2.0C in the coming years. !• A “climate fund” will be created by developed nations to help developing nations to shift to renewable energy. It estimates to reach US$ 100 billion by 2020.!
Global coal production – past and future.!An analysis reveals that global coal production may still increase over the next10 to 15 years by about 30 percent, mainly driven by Australia, China, India,the Former Soviet Union countries and South Africa. Production will then reacha plateau and will eventually decline thereafter. The possible production growthuntil about 2020 according to this analysis is in line with the two demandscenarios of the International Energy Agency (IEA). !
Potentials of Renewable Energy - Wind!Although wind has been a reasonable alternative, it canʼt be stretched as the potential of wind is !limited, especially in rapid developing countries such as China, India and Brazil. Also, because of !the lack of technological advancement, the cost will remain high compared to PV.!
Potentials of Renewable Energy - Hydro!As you can see, the global theoretical potential of Hydro is very low to consider it as an !serious alternative.!
Potentials of Renewable Energy – Solar PV Centralized!The density relates to the horizontal surface area potential which are calculated for !solar power plants, which requires optical concentration.!
Potentials of Renewable Energy – Solar PV decentralized!The density relates to the tilted module area, which are calculated for buildings. As you !can see, most of the developing nations have above average solar concentration.!
Potentials of Renewable Energy – Solar Thermal!The density reveals the solar concentration which are optimal for solar thermal power !generation. !
The density maps shows us that most of the developingcountries, which are high energy consuming, possess enoughsolar radiation to support their energy demand.!!The countries which donʼt have solar radiation are mostlydeveloped and their growing need for energy is very low. Theyalso have plenty of wind.!!
Transforming the global energy mix. Exemplary path until 2050/2100.!This calculated table shows how the energy generation through oil and coal will gradually !come down thereby pushing solar PV as the primary source of energy generation.!
Transforming the global energy mix. Exemplary path until 2050/2100.!
All these facts demonstrates that Solar Photovoltaic is the major and promising !alternative that can replace coal and oil.!!Few indications:!1. The PV sectors revenue reached US$ 17.2 billion in 2008.!2. The PV production growth globally was 69% in 2007.!3. The sector has shown consistent growth of 40% for the past 6 years.!4. The cost of solar electricity is dropping approx. 8% each year, therefore !reaching grid parity in less than a decade.!5. PV installation increased from 1,000 MW in 2004 to 23,000 MW by 2009.!!!
“Our vision is to make Indiaʼs economic development energy-efﬁcient. Over a period of time, wemust pioneer a graduated shift from economic activity based on fossil fuels to one based onnon-fossil fuels and from reliance on non-renewable and depleting sources of energy torenewable sources of energy. In this strategy, the sun occupies center-stage, as it should, beingliterally the original source of all energy. We will pool our scientiﬁc, technical and managerialtalents, with sufﬁcient ﬁnancial resources, to develop solar energy as a source of abundantenergy to power our economy and to transform the lives of our people. Our success in thisendeavor will change the face of India. It would also enable India to help change the destinies ofpeople around the world.”!!~ Dr. Manmohan Singh, the Prime Minister of India, 2009.! Gokul Basker! email@example.com!
