Tidal energy uses gravitational pull of Earth, moon and sun to produce energy where as a wave energy uses kinetic forces of waves to generate electricity. The tides at shorelines of oceans will rise and fall about twice a day. 

Solar energy is the energy derived from sun’s heat and light. It is an important source of renewable energy. Direct Solar energy is used for Water heating, Distillation, Drying, solar thermal energy, solar architecture, molten salt power plants, artificial photosynthesis etc.

Madhapur near Bhuj in Gujarat is the largest producer of solar energy.

India is a tropical country. It has enormous possibilities for tapping solar energy. Photovoltaic technology converts sunlight directly into electricity. Solar energy is fast becoming popular in rural and remote areas. Some big solar power plants are being established in different parts of India.

Renewable energy is used to describe energy sources that are replenished by natural processes on a sufficiently rapid time-scale so that they can be used by humans more or less indefinitely, provided the quantity taken per unit of time is not too great. Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth.

• Mining is extraction of valuable minerals or other geological materials from the earth usually from an orebody, lode, vein, seam, reef or placer deposits.

• Mining has the potential to shape and affect economies directly and indirectly. Mining brings employment, government revenues, and opportunities for economic growth and diversification.

• Mining  is called a robber industry because valuable resources are taken from the earth and hence depriving earth from it's own resources 
  
• .These resources are not formed in a small time instead takes millions of years to replenish.
  
• This is because it is using up the earths resources, therefore in a very poetic sense 'robbing' the earth of its natural resources that will not be laid down again, at least not for an extremely long period of time
