(i) Wind energy is the energy that is harnessed by the movement of the flowing wind. It has been in use for many years in rural areas under the wind energy farms. In the recent years, wind energy has gained immense popularity worldwide. Over the years efforts have been made to make the wind power generators more efficient and practical. For example, windmills for generating mechanical power, wind turbines to produce electricity, etc.


(ii) Tidal energy refers to the energy derived from the tides of the sea. As we know high and low tides are created in the sea are generated by the gravitational pull of the moon and the rotation of the earth. Tidal energy is the energy derived from such tides. For example, tidal barrages are used to capture the tidal energy to produce energy.


(iii) It is often said' Health is Wealth'. For a person to be healthy he/she should be physically, mentally as well as socially well. That is, health is not only mere absence of diseases but also includes the state of complete physical, mental, and social well-being of an individual. Health improves the overall quality of life of a person along with his efficiency and productivity. Consequently, it contributes actively towards the growth and development of the society. Thus, to ensure a healthy manpower is of utmost importance for a nation. For this, a country develops health infrastructure. Health infrastructure includes hospitals, doctors, dispensaries, nurses, medical technology, equipment, pharmaceutical industry, paramedical professional, etc. Every nation tries not only to ensure the development of such health infrastructure but also that it is accessible by the masses.
