SCIENCE

Harnessing energy from renewable sources such as wind, solar, and biomass is essential for sustainable development. Wind energy, captured through turbines, converts wind into electricity.

Ways to save energy.

11.Service all your appliances on a regular basis, so that they work efficiently without consuming too much energy.
10.Don't leave the shower on when you don't need it while bathing. This will help you save both a lot of water and electricity.
9.Use water heaters that function on solar power. Don't allow your water heater to be on for longer than you need it
8.Don't spoil yourself and your kids by using your car to take you everywhere. Instead use alternative energy sources that will also give you some exercise apart from saving energy. Try cycling, skating, or walking to your destination. It allows your to spend more time together, and keeps your healthy too.
7.One of the many ways to save energy at home is to ensure that you don't leave the refrigerator door open for too long while deciding what you want from it. Doing so consumes a lot of electricity, and may also spoil your refrigerator over time.
6.With winters around, set your thermostat at 68 degrees during the day and at 55 degrees during the evening to keep cozy. This temperature keeps you warm enough and also consumes lesser energy.
5.Make the most of solar energy by hanging your clothes out to dry in the sun rather than using your dryer. This method not only saves energy, but has your clothes smelling and feeling fresh!
4.Choose appliances that all have energy star ratings. All these use much lesser energy and function as efficiently as any other electronic appliances.
3.Do not leave your electronic appliance on standby.Though not in use, these electronics consume a lot of energy and up your bills tremendously.
2.Use only energy saving lights known as CFLs that save about 20%-30% energy and help you reduce your bills.
1.Start by remembering to switch off all your lights and fans when you leave the room.

Light energy(Luminous energy)

Light energy is the energy that enables us to see.The SI unit of luminous energy is the lumen second(lm/s).

MUSIC ;Made by the mixture of sound and light energy!

Electrical energy

Electricity or eletrical energy is the energy that results from the flow of charged particles.

Sound energy

Sound energy is the energy produced when objects vibrate.

Renewable energy

Renewable Energy is a form of energy generated from natural resources like wind, sunlight, rain, tides and geothermal heat. They are naturally replenished and are not easily exhausted.

Biomass energy

Biomass energy resources can be efficiently used to solve most of the energy-related problems that we face today

Wind energy

The all pervasive wind when harnessed properly to gain another form of energy it is the wind power at work. Wind power is most often used to generate electricity through turbines.

Solar energy

The radiations and heat of the sun and power generated through it is collectively called solar energy.

Heat energy(Thermal energy)

Heat energy is the energy that flows from regions of higher temperature to one at lower temperature.

Geothermal Energy

This is the energy that is generated from the radioactive decay of various natural minerals and from volcanic activities that is contained in the earth's crust. This thermal energy is both produced by and stored inside the earth's crust.

Ocean Thermal Energy

This type of thermal energy is harnessed by utilizing the difference between the temperatures of the deep and shallow water areas in the oceans.

Solar Thermal Energy

This is perhaps the most commonly harnessed thermal energy form we can see around us.

Kinectic energy

Kinetic energy is the energy that a body has due to its motion.

Relativistic Kinetic Energy
Rotational Kinetic Energy

this energy comes through rotation of the object along some specific axis of rotation.Example are;Flywheels, planets and stars rotate on their own axis called as spin rotational kinetic energy.

Rotational kinetic energy is an integral part of the total kinetic energy of a system that is possessed by the virtue of motion of the object about an axis of rotation. Stated simply, the energy possessed by rotation of rigid body about any line through the center of mass, is rotational kinetic energy

Potential n Kinectic energy

Potential energy

Potential energy is the energy that stored energy dur to a body's position or condition.

Elastic potential energy

Elastic potential energy is the energy an object has when it is streched or composed.

Gravitational potential energy

Gravitational potential energy is the energy an object has because its position or location,i.e.when it is in a higher position with respect to the ground,it has more gravitational potential energy than in a lower position.

Chemical potential energy

Chemical potential energy is the energy stored in fuels such as pestrol and food that can be released through chemical reactions.
