Energy Resources and Storage

Solar energy is the energy which is available from the sun. It is most readily available source of energy. It is the inexhaustible source of energy because energy from sun will never exhaust. It is also the most important of the non-conventional sources of energy because it is non-polluting and, therefore, helps in lessening the greenhouse effect.

Tidal energy is a replenishable energy. The replenishable resources are capable of being used over and over again and are capable of regeneration. They are inexaustible resources and their quantity is vast, unlimited, e.g., water, wind, plant.

Non- conventional sources of energy are those which have been developed in the recent past as an alternative to conventional sources of energy. These include solar energy, wind energy, tidal energy, geothermal energy, nuclear energy and biogas. They are renewable and therefore, inexhaustible, non-polluting, less expensive and easy to maintain.

Solar energy: Energy from sun is called solar energy and it is the most abundant source of energy.

Geo-thermal energy: It is the heat energy contained in the rock and fluid that fills the fractures and pores within the rock in the earth's crust. It is clean and sustainable.

Tidal energy: Energy generated from tides is called tidal energy. Tidal energy can be harnessed by building dams at narrow openings of the sea. The Gulf of Kuch is best suited for tidal energy.

Sunlight, water, wind and biomass are the non-conventional sources of energy. Non-conventional sources are replenishable and safe to ecology. Non-conventional means not widely in use.

Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environmental pollution. Moreover, they do not require heavy expenditure.

Energy generated from natural sources like wind, tides, solar, geothermal heat, and biomass including farm and animal wastes is called non-conventional energy. It has following features like: it is pollution free, they are renewable and are abundant in nature. Among the given options petroleum is not an example of non-conventional energy resource.

Energy generated from natural sources like wind, tides, solar, geothermal heat, and biomass including farm and animal wastes is called non-conventional energy. It has following features like: it is pollution free, they are renewable and are abundant in nature.

Wind turbines convert the mechanical energy of spinning blades into electrical energy via an electromagnetic generator. This is the standard process for wind power generation.

Wind possesses kinetic energy due to its motion. When it strikes the turbine blades, it causes them to rotate, which is a form of mechanical energy.

A skier at the top of a hill is stationary, meaning they possess gravitational potential energy rather than kinetic energy. The other options describe objects currently in motion.

Wind and water turbines are specifically designed to capture the kinetic energy of moving air or water and convert it into electrical energy using a generator.

Construction is the field of technology focused on building structures that support loads and provide shelter or protection from the environment.

Charles Fritz is credited with creating the first solar cell using selenium in 1883.

Coal is a fossil fuel that contains stored chemical energy. When burned, this energy is released as heat, which is used to boil water, create steam, and turn turbines to generate electricity.

Wood is a renewable resource because trees can be replanted and grown within a human timeframe. Iron, oil, and sand are nonrenewable on a human timescale.
