Introduction

• Energy is a major input for overall socio-economic development

of any society

• The prices of the fossil fuels steeply increasing

• So renewables are expected to play a key role

• Wind energy is the fastest growing renewable

• Wind turbines are up to the task of producing serious amounts

of electricity

Renewable Energy: India Scenario

• India is giving a strong push to renewable energy in line with its commitment to cut carbon emissions by 35% and increase the use of renewable energy sources to generate at least 40% of its power needs by 2030.

• In line with the Paris Climate Agreement, Ministry of New & Renewable Energy, Government of India announced the renewable energy target of installing 175 GW capacity by 2022.

• Wind power accounts for 63.2% of the total installed capacity of renewable energy in India.

• India ranks fourth in the world in wind power installed capacity with an installed capacity of 26,769 MW

• The government targets capacity addition of 88.5 GW under the 12th

Five-Year Plan (2012–17) and around 100 GW under the 13th Five-Year Plan (2017–22)

Renewable Energy: India Scenario

As on 31st March 2016, total installed power capacity from renewable energy sources(excluding Hydro Power) was 43.7 GW. This accounts for ~14% of the total installed

power capacity

Renewable Energy: India Scenario Wind Energy

Wind power has the highest share in the installed capacity of renewable energy in India

• India has a substantial wind power potential, estimated by India’s National Institute of Wind Energy at around 302GW for onshore wind turbine installations with a hub height of 100 meters.

• The most promising sites are in the west and south, with around 90% of the potential in the states of Tamil Nadu, Andhra Pradesh, Madhya Pradesh, Karnataka, Maharashtra and Gujarat.

• Wind power generation is projected to increase strongly, with installed capacity rising from 26.9GW to 142GW in 2040.

• Y ear 2015-16 saw the highest ever capacityaddition of 3515 MW.

Basic of Wind Turbine

• Uneven heating results in a difference in atmospheric pressure, which causes the air to move.

• The kinetic energy of the moving air (or wind) is transformed into electrical energy by wind turbines or wind energy conversion systems.

• Wind turbine’s blades convert kinetic energy from the movement of air into rotational energy; a generator then converts this rotational energy to electricity via electromagnetic induction.

• The main factors of the output power are the wind speed and the length of the blades.

Implementation In Wind Energy Technology

• Technological innovation is a key factor for future wind power development. The growth of wind energy in India has been very consistent.

• For instance, we’re able to use winds with starting speeds as low as 1.5 (m/s). Also, we could operate in winds exceeding 40 m/s.

• It would also increase generation capacity by 20% over conventional wind turbines and decrease operational costs by 50%.

• In most states rural power supply is intermittent and of poor quality. New generation capacity must be built, and given the affordability and concerns of marginal consumers, renewables with minimal cost inflation suit it best.

• The Implementation includes starting offshore wind energy installation, repowering of old turbines with new higher capacity wind turbines, Innovations Small wind turbines, better aerodynamic profile.

Implementation In Wind Energy Technology

• Magnetic levitation, maglev or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields.

• The Magenn Air Rotor System (MARS) is the next generation of wind turbines with cost and performance advantages over existing systems.

• Vertical-axis wind turbines are a type of wind turbine where the main rotor shaft is set vertically. generators and gearboxes can be placed close to the ground.

• The main types of VAWT are Savonius, Darrieus and Giromill designs as shown in Fig

Socio Economic Growth of Renewable Energy

12

Socio Economic Growth of RE

• India’s renewable energy market is among the major and fastest growing markets in the world.

• India faced with the challenge of a growing population, provision of rural electrification, and deep energy shortages, simply had to grow all generation sources

• The imperative to add substantial new generation capacity to meet social and economic needs is helping India reshape its energy mix towards renewables quicker than other regions.

• Rural electrification and provision of 24X7 power supply is a key priority for the government.

POWER• With a production of 1,278.91 TWh, India is

the third largest producer and the fourth largest consumer of electricity in the world.

• Although power generation has grown more than 100-fold since independence, growth in demand has been even higher due to accelerating economic activity.

India Among Top Four Power Producers And Consumers

• Demand for electricity is expected to increase at a CAGR of 7 per cent to 1,894.7 TWh over FY07–22

• Current production levels are not enough to meet demand; annual demand outstrips supply by about 7.5 per cent

• All India per capita consumption of electricity is expected to reach 1000 KWh by FY15

14

• Promoting rural energy for productive uses and linked social benefits.

• Promoting renewable energy for rural electrification and industrial applications.

• Enhancing access of the rural poor to affordable and sustainable energy services.

• Supporting training and capacity building for manufacture, local assembly and maintenance of renewable energy technologies.

• Organizing global forum activities and providing strategic expert advice on renewable energy technologies and energy policy planning and institutional framework.

Current Focus To Increase Socio Economic Growth

15

Increase Use of Renewables• There are different ways in which maximum use of wind energy in different

locations in India where we can reduce dependency on non- renewables.

• Implementation of wind energy sources is vital to meet the growing energy demand in India.

• India has huge potential of renewable energy sources especially wind. Realizing this potential, Government of India should actively put efforts to promote renewable energy.

• Wind energy has very good potential. it is the fastest growing energy source and further Implementation will decrease dependency on Non renewables.

• The future looks bright for wind energy because technology is becoming more advanced and windmills are becoming more efficient.
