Energy

What is energy?

Energy is the ability to do work.

Energy cannot be created nor destroyed only transformed.

Types of Energy

Non-renewable energyRenewable energy

Non-renewable Energy

Non-renewable resources are natural resources that cannot be re-made or re-grown at a scale comparable to its consumption.

Non-renewable energy is the energy from uranium and fossil fuels which are coal, crude oil (petroleum) and natural gas.

Renewable Energy

Renewable resources are natural resources that can be replenished in a short period of time.

Renewable energy includes biomass, wind, hydro-power, geothermal and solar sources.

Non-petroleum-dependent technology

Non-petroleum-dependent technologies are the technologies that do not use energy from fossil fuels.

Environmental Impact

Non-renewable energy resources have a negative effect on the environment. Burning oil and natural gas emit carbon dioxide and other pollutants, contributing to global climate change.In addition, coal processing plants leach toxic metals into ground and water.

Running out of non-renewable resources

World is consuming more non-renewable resources and finding less.

Solar Energy and How It Works

Solar power is the energy from the sun.

This energy can be converted into other forms of energy,

such as heat and electricity.

Solar Cells

Solar cells are devices that convert light energy

directly into electrical energy.

These cells use semiconductors.

Solar Panels

Solar panels do not generate electricity directly.

Instead they heat up water directly.

Wind Energy

Wind is a renewable energy source because the wind will blow as long as

the sun shines.

Just like windmills, today’s wind turbines use blades to collect the wind’s

kinetic energy. The wind flows over the blades creating lift, like the effect on

airplanewings, which causes them to turn. The blades are connected to

a drive

shaft that turns an electric generator to produce electricity.

Geothermal EnergyIn some places the rocks underground are hot. It

returns tothe surface as hot water and steam, where its energy

can be used to drive turbines and electricity generators.

Hydro EnergyHydropower or water power is power derived from the energy of

falling water.Though some flowing areas were made intentionally for this

renewableenergy source but this is capable of destroying natural habitats

andbiodiversity of aquatic animals. A solution has been made for fish that migrate up stream to

spawn; it iscalled a fish ladder.

Biomass EnergyBiomass is organic material made from plants and animals(microorganisms)that contains stored energy from the sun.

Plantsabsorb the energy through photosynthesis. The chemical

energy inplants gets passed on to animals and people that eat them.

When burned, the chemical energy in biomass is released

as heat.If you have a fireplace, the wood you burn in it is a biomass

fuel.

Conclusions

This world does not belong to us only, it belongs to everyone.

So, we have to take care of it for the future generations.

“Only when the last tree will be cut, the last river will be

poisoned and the last fish will be caught, we will realize that

we cannot eat money”.
