Energy indisputably a resource on which humanity has been dependent. Without energy, we cannot find or administer medicine to cure disease, prepare food, purify water, drive our cars etc. the current energy need is 15TW and this number is projected to increase.in now a days we are more reliable on fossil fuel. Fossil fuels are also a large source pollution and also a non-renewable source of energy. As solar energy is a renewable source of energy so we are likely to shift our energy consumption from the non-renewable forms to the renewable forms.
Wind power or wind energy is wind energy, which is used to provide mechanical power by wind turbines to produce electricity and to do other jobs, such as milling or pumping. Wind energy is clean, renewable and has far less environmental impacts than fossil fuel use.
Wind farms consist of several individual wind turbines linked to the power supply grid. Onshore wind is a reliable power source, comparable with or much cheaper than coal or gas plants. Onshore wind turbines will have an effect on the environment, as usually they may spread over more land than other power plants and be installed in wild and remote areas that could result in ‘rural industrialisation’ and loss of habitat. Offshore winds are more steady and strong than on land and offshore farms, but building and repair costs are higher.
The wind is an intermittent source of energy that neither produces nor ships electricity on demand. It also offers a variable power that varies widely year after year, but over shorter periods. It must also be used in combination with other sources of energy or storage to provide secure supplies. With the share of wind power in a region increasing, more traditional energy sources (such as fossil fuels and nuclear power) are required to help them, and the network will need to be upgraded. Such energy management strategies may also solve problems, such as a dispatching energy, an adequate hydro-electric energy, surplus capacity, geographically dispersed turbines, export and import power to neighbouring areas, electricity storage or a reduction in demand when wind turbines are low. The weather forecast allows for predictable output fluctuations in the electricity network.
In recent years, the capacity to produce wind energy has increased significantly in India. As of 29 February 2020, the wind turbines had an installed wind energy capacity of 37.669 GW and it was the fourth highest installed wind power capacity in the world.
In India, the cost of wind power is rapidly declining. During December 2017 auctions on wind projects, the uniform tariff on wind turbines reached a record low of 2,43 kWh (3,4 US), per kWh (without any direct or indirect grants). In December 2017, the Union government announced the relevant Tariff Wind Power Auction Guidelines in order to provide the developers with clarification and to reduce the risk.
