Question

write short note on energy resources​

Answer 1

Answer:

Energy Resources. Energy is the capacity to do work and is required for life processes. An energy resource is something that can produce heat, power life, move objects, or produce electricity. Matter that stores energy is called a fuel.

hope it helps dear.

Answer 2

The Answer is:

Energy is the ability to accomplish work and is essential for living processes. An energy resource is something that can provide heat, power life, move objects, or generate electricity. A fuel is defined as matter that stores energy.

• Human energy consumption has continually increased throughout history. Early humans' energy requirements were minimal, consisting primarily of food and fuel for fires used to cook and keep warm.
• Humans today consume up to 110 times the amount of energy that early humans did.
• The majority of the energy we consume today comes from fossil fuels (stored solar energy). However, fossil fuels have a disadvantage in that they are non-renewable.

There are five primary sources of energy:

• The Sun's nuclear fusion (solar energy)
• The Earth and Moon generate gravity.
• Fission reactions in nuclear reactors.
• Energy found deep within the Earth.
• Chemical bonds store energy.

Solar Power:

• Solar energy is emitted by the Sun as electromagnetic radiation. It can be directly utilised for heating or turned to power for other purposes. It is an almost limitless source, renewable, and mostly non-polluting.

The Earth and Moon generate gravity:

• Tides are caused by the Moon's gravitational pull on Earth. Tidal flow can be used to power turbines. This is also a virtually limitless source of energy that is mostly non-polluting.

Fission reactions in nuclear reactors:

• Radioactive Uranium is concentrated and formed into fuel rods, which emit significant amounts of heat due to radioactive decay. Water is converted to steam with this heat. Steam expansion can then be used to power a turbine and create electricity.

Energy found deep within the Earth:

• Throughout Earth's history, radioactive element decay has produced heat. This heat is responsible for the Earth's temperature rising with depth and for the melting of mantle rocks to generate magmas. Groundwater circulating near igneous intrusions transports heat back to the surface. When held at deep depths under pressure, it can be converted into steam, which expands and drives a turbine.

Chemical Bonds Store Energy

• Chemical processes are propelled by the energy stored in chemical bonds. This energy is either emitted or absorbed as the reactions occur. It is kept in the chemical bond for subsequent usage if it is absorbed. It can generate valuable heat energy if released. Light and electricity
