- 11. COMMERCIAL AND NON COMMERCIAL ENERGY • COMMERCIAL ENERGY : – Energy source that are available in market for definite prices are known as Commercial energy. – They forms the basis of industrial, agricultural, transport and commercial development in the modern world . – Eg : Electricity, lignite, coal, oil, natural gas Dept of Mechanical Engineering 16MEE43 - SOLAR AND WIND ENERGY 11
- 12. • NON COMMERCIAL ENERGY: – The energy sources that are not available in the commercial market for a price are classified as non-commercial energy. – Eg: Firewood, agro waste in rural areas; solar energy for water heating, electricity generation, for drying grain, fish and fruits; animal power for transport, threshing, lifting water for irrigation, crushing sugarcane.

- 14. GLOBAL ENERGY RESERVES Coal : – Global coal reserve was estimated to be 1.1 trillion tonnes of proven coal reserves worldwide. – The USA had the largest share of the global reserve (25.4%) followed by Russia (15.9%), China (11.6%) ,India (8.6%). Oil : – British oil company (BP) estimated that the world had 1.73 trillion barrels of oil reserves as of 2018, which would be sufficient to meet 50 years of global production at 2018 levels. – Saudi Arabia had the largest share of the reserve with almost 23%. Gas : – As of January 1, 2019, there were an estimated 7,177 trillion cubic feet (Tcf) of total world proved reserves of gross natural gas. – The Russian Federation had the largest share of the reserve with almost 27%.

INDIAN ENERGY SCENARIO • Coal dominates the energy mix in India, contributing to 55% of the total primary energy production . • Coal in India has been mined since 1774 and is now the second fastest mined in the world, producing 716 million metric tons (789 million short tons) in 2018 • The estimated reserves of crude oil in India as on 31.03.2018 stood at 594.49million tonnes (MT) against 604.10 million tonnes on 31.03.2017 • Oil accounts for about 36 % of India's total energy consumption • The estimated reserves of Natural Gas in India as on 31.03.2018 stood at 1339.57Billion Cubic Meters (BCM) as against 1289.70 BCM as on 31.03.2017 • Natural gas accounts for about 8.9 per cent of energy consumption in the country . • Nuclear Power contributes to about 2.4 per cent of electricity generated in India.

- 20. ENERGY NEEDS OF GROWING ECONOMY • Economic growth is desirable for developing countries, and energy is essential for economic growth. • For example, under present conditions, 6% increase in India's Gross Domestic Product (GDP) would impose an increased demand of 9 % on its energy sector. • The ratio of energy demand to GDP is a useful indicator • A high ratio reflects energy dependence and a strong influence of energy on GDP growth. • Energy intensity is energy consumption per unit of GDP. Energy intensity indicates the development stage of the country. • India’s energy intensity is 3.7 times of Japan, 1.55 times of USA, 1.47 times of Asia and 1.5 times of World average.

- 22. • The usage of energy resources in industry leads to environmental damages by polluting the atmosphere. • Few of examples of air pollution are sulphur dioxide (SO2), nitrous oxide (NOX) and carbon monoxide (CO) emissions from boilers and furnaces • Chloro-fluro carbons (CFC) emissions from refrigerants use. • In chemical and fertilizers industries, toxic gases are released. • Cement plants and power plants spew out particulate matter.

- 25. ENERGY SECURITY • The basic aim of energy security for a nation is to reduce its dependency on the imported energy sources for its economic growth. • India will continue to experience an energy supply shortfall throughout the forecast period. This gap has widened since 1985, when the country became a net importer of coal. • Rising oil demand of close to 10 percent per year has led to sizable oil import bills. Dept of Mechanical Engineering 16MEE43 - SOLAR AND WIND ENERGY 25
- 26. • Some of the strategies that can be used to meet future challenges to their energy security are Diversification of energy supply sources Increased capacity of fuel switching Development of renewable energy sources.
