And people have made a lot of progress in this field. In wildlife conservation‚ people try their best to protect endangered plants and animals‚ as well as their habitats. The purpose is to make sure that future generations will have enough space to survive and develop well. Countries all over the world have different agencies for wildlife

Energy Resources and their Uses in Producing Electricity Renewable energy is energy drawn from natural processes that are restored quicker than they are used up‚ some renewable energy resources are biomass‚ food‚ wind‚ waves‚ flowing water‚ solar and geothermal. The sun however‚ is known to be the ultimate energy resource since almost all energy resources originate from the sun’s energy. This is possible according to the law of conservation of energy which states that energy can’t be destroyed

Because wet (water) by grinding effect‚ and water is the simplest‚ cheapest‚ "aids." Its will to a large extent influence the fragmentation of materials. Adsorbing water because of the solid surface (the activity of a molecule)‚ the surface free energy and the elastic deformation can be reduced‚ resulting in the weakening bond together to promote and accelerate the materials

improvised washing machine to lessen the physical burden of women doing laundry by hands. It will lessen the time of washing clothes‚ conserves energy and is environmental friendly. It is also made out of locally available and dumped materials. This eco-friendly laundry machine is cheaper than the commercial one. This will contribute a lot in electrical energy conservation. Yes‚ it is made of dumped materials but because of creativity and resourcefulness‚ we had come up with this useful machine. This machine

What is kinetic energy? Kinetic energy is energy due to object’s motion. Kinetic energy of an object depends on both its mass and its speed. Kinetic energy increases when mass increases. You can find kinetic energy by using the formula kinetic energy equals one half times mass times speed to the second power. What is potential energy? Some objects have stored energy as a result of their positions or shape.Potential energy is stored energy that results from the position or shape of an object.

should use solar energy in order to conserve environment. State whether you agree or disagree with this statement and support your opinion by referring to appropriate sources. In current society‚ the problem of the climate issue and of the finite nature of fossil energy sources is becoming increasingly serious. The need of renewable and clean energy becomes extremely urgent. But in the meantime‚ solar energy as new type energy cause people concern. In addition‚ whether using solar energy to protect environment
