presentation of energy and its uses

let's start!!!

• Important of energy resources
• conventional energy sources
• Non conventional energy sources (Solar Energy, Wind Energy etc and its uses)

energy and its USES

• Energy is all around us.

• he topic of the importance of energy sources is a conversation that will continue over the next few decades as more people begin to realize the value of utilizing renewable energy as opposed to getting energy from sources that don't naturally regenerate

• It’s responsible for making everything happen, whether you want to use any household appliance, take a walk through the park, drive your car across town, or do anything that involves movement or activity.

• It’s also necessary in abundance for all types of modern conveniences, from light bulbs to appliances to vehicles.

• Energy is essential to life and all living organisms.

• The sun, directly or indirectly, is the source of all the energy available on Earth.

Important of Energy Resources

• Our energy choices and decisions impact Earth's natural systems in ways we may not be aware of, so it is essential that we choose our energy sources carefully.

• Energy is one of the most important inputs for economic development.

• From a physical viewpoint, the use of energy drives economic productivity and industrial growth and is central to the operation of any modern economy.

• The true cost of energy is more than just dollars and cents; there are important economic, political and social factors and consequences to consider as well.

• These energy resources can be classified as Conventional and Non-conventional sources of energy.

• Let us see how they differ from each other!

Using these sources is less expensive.

Heavy expenditure is involved in using and maintaining these sources of energy.

They are not used as extensively as conventional sources.

They are used extensively, at a higher rate than the non-conventional sources.

Non-conventional energy sources are eco-friendly in nature.

These resources are available in a limited quantity.

Non-conventional energy resources are renewable.

The conventional sources of energy are non renewable by any natural process.

Solar Energy, Wind Energy, Tidal Energy, geothermal energy,Bio Energy, Hydro Energy, Ocean Energy are the examples of non-conventional energy resources.

Fossil fuel, CNG, coal, oil, natural gas are the examples of the conventional sources of energy.

The differences between conventional and non-conventional energy sources are as follows-

conventional energy

non-conventional energy

Conventional sources of energy :

• Conventional sources of energy are the natural energy resources which are present in a limited quantity and are being used for a long time.

• They are called non-renewable sources as once they are depleted, they cannot be generated at the speed which can sustain its consumption rate.

• They are formed from decaying matter over hundreds of millions of years.

• These resources have been depleted to a great extent due to their continuous exploitation.

• It is believed that the deposits of petroleum in our country will be exhausted within few decades and the coal reserves can last for a hundred more years. Some common examples of conventional sources of energy include coal, petroleum, natural gas and electricity.

Non - Conventional sources of energy :

• Non-conventional sources of energy are the energy sources which are continuously replenished by natural processes.

• These cannot be exhausted easily, can be generated constantly so can be used again and again.

• E.g. solar energy, wind energy, tidal energy, biomass energy and geothermal energy etc.

• The energy obtained from non-conventional sources is known as non-conventional 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

Some of Most Popular Non - Conventional Sources of Energy :

BIOMASS ENERGY

TIDAL ENERGY

GEOTHERMAL ENERGY

WIND ENERGY

COMPARISON

SOLAR ENERGY

• Light energy and heat energy from the sun are known as solar energy.

• Sun has been radiating energy from the past 5 billion years and will continue to do so at the same rate for another 5 billion years or more.

• We must find ways to harness the energy with maximum efficiency, although only a small fraction of the solar energy reaches the earth’s surface.

• Solar energy is defined as the transformation of energy that is present in the sun and is one of the renewable energies.

• Once the sunlight passes through the earth’s atmosphere, most of it is in the form of visible light and infrared radiation.

• Plants use it to convert into sugar and starches and this process of conversion is known as photosynthesis.

• Solar cell panels are used to convert this energy into electricity

1. Solar Energy :

• Solar heating

• Generate Electricity

• Cooking(Solar Cooker)

• Charging Batteries

• Solar Transportation

• Solar Ventilation

• Solar Transportation

• Solar Energy for Houses

• Solar Energy for Industries

Uses Of Solar Energy :

• Wind energy describes the process by which wind is used to generate electricity.

• Wind energy refers to capturing the energy from moving air, i.e., wind, and converting it into electricity.

• Wind turbines convert the kinetic energy in the wind into mechanical power.

• As a renewable resource that won't get depleted through use, its impact on the environment and climate crisis is significantly smaller than burning fossil fuels.

• Wind energy can be created by something as simple as a set of 8-foot sails positioned to capture prevailing winds that then turn a stone and grind grain (a gristmill).

• Wind power is one of the fastest-growing renewable energy technologies.

2. Wind Energy :

• Now-a-days wind energy is being used to generate electricity.

• The wind energy is used to propel the sailboats in river and seas to transport men and materials from one place to another.

• Wind energy is used to run pumps to draw water from the grounds through wind mills.

• Wind energy has also been used to run flourmills to grind the grains like wheat and corn into flour.

Uses Of Wind Energy :

• It is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity.

• Tidal power is extracted from the Earth's oceanic tides, tidal forces are periodic variations in gravitational attraction exerted by celestial bodies.

• These forces create corresponding motions or currents in the world's oceans.

• Tides are variations in the level of water due to the gravitational pull of the moon.

• The phenomenon of rise and fall of water level or high and low tide gives tidal energy.

• It is limited to places near the sea.

3. Tidal Energy :

• We can use tidal energy to supply electricity to our homes and businesses.

• We can use tidal energy in some places instead of burning coal and oil that contribute to global warming.

• Tidal generators (or turbines) work like wind turbines, except it is ocean currents, not wind, that turns them.

Uses Of Tidal Energy :

• It is formed by residue and waste of plants and other living matter, agricultural and forests waste, organic effluents from industries like sugar, slaughter etc.

• Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals.

• Biomass contributes 15% of total energy supplied world wide.

• It has a draw back that it needs to go throug several steps like grown, collected, dried, fermanted and burnt. This requires resources and infrastructures.

• Biomass, as a renewable energy source, is biological material from living, or recently living organisms.

• Biomass Energy The power plant will generate about 4800 units of celectricity/day.

• The power generated from the plant will be sold at Rs.3.15/unit.

• The most common biomass materials used for energy are plants, wood, and waste.

4. Biomass Energy :

• Biomass can be used for fuels, power production, and products that would otherwise be made from fossil fuels.

• Biobased feedstocks can be used to produce a range of personal care products, such as skin cream, shampoo and more.

• Food Additives And Nutritional Supplements.

Uses Of Biomass Energy :

• It comes from radioactive decay from the core of the earth which heats earth from the inside out, thus energy can be extracted.

• Geothermal energy is the heat that comes from the sub-surface of the earth.

• This requires that hot rock be relatively shallow,so it is site-specific and can only be applied in geologically active areas.

• Geothermal power plants are built where geothermal reservoir are located with in a mile of the surface.

• Geothermal heat pumps use stable ground or water temperature near the earth's surface to control building temperature above ground.

5.Geothermal Energy :

• Geothermal energy is used to directly heat individual buildings and to heat multiple buildings with district heating systems.

• Hot water near the earth's surface is piped into buildings for heat.

• A district heating system provides heat for most of the buildings in Reykjavik, Iceland.

Uses Of Geothermal Energy :
