What are 2 disadvantages of wind energy?
Turbines might cause noise and aesthetic pollution.
Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape.
Why are non-conventional sources of energy are better than conventional sources of energy?
Answer: Non-conventional sources of energy: These sources do not pollute the environment and do not require heavy expenditure. They are called renewable resources as they can be replaced through natural processes at a rate equal to or greater than the rate at which they are consumed.
What are the limitations of non-conventional energy in India?
The electricity generation capacity from non-conventional sources is still not enough to fulfill the demands of the a huge population. Renewable energy can be unreliable since it entirely depends on the weather. Requires huge capital for the installation of wind turbine, solar panels, and hydroelectricity plants.
What are the limitations of exploiting non-conventional energy resources?
5.3 DISADVANTAGES
- They are subject to influence of natural forces and therefore their availability varies from day to night and also from season that is these plants cannot provide a steady continuous supply of energy.
- Initial investment cost is high and at present technological development stage it is not very cost.
Why should we use non-conventional sources of energy?
Why do we need non-conventional energy resources? As the consumption of energy grows, the population depends more and more on fossil fuels such as coal, oil and gas day by day. There is a need to secure the energy supply for future since the prices of gas and oil keep rising by each passing day.Which of the following is NOT a non-conventional sources of energy?
Thermal Energy is not one of the non-conventional sources of energy in India. Thermal energy is the energy that comes from heat.
Why is energy crisis a problem?
The energy crisis is the concern that the world’s demands on the limited natural resources that are used to power industrial society are diminishing as the demand rises. These natural resources are in limited supply.
