Energy
What is energy?
Energy is the ability to do work.
Energy cannot be created nor destroyed only transformed.

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.
![Page 13: The Widespread Use of Non-petroleum-Dependent Technology](https://reader033.fdocuments.us/reader033/viewer/2022052701/55cf96a3550346d0338cd556/html5/thumbnails/13.jpg)
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.
![Page 17: The Widespread Use of Non-petroleum-Dependent Technology](https://reader033.fdocuments.us/reader033/viewer/2022052701/55cf96a3550346d0338cd556/html5/thumbnails/17.jpg)
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”.
