Energy Resources

Energy resources are subdivided into two groups: renewable resource of energy and non renewable resource of energy. Renewable resources are those that can be replenished in a short period of time, while non renewable energy resources are those which we are constantly using up and cannot create in a short span of time.

Renewable energy resources include the solar energy, wind energy, wave and tidal energy, geothermal energy, biomass and hydropower. These are clean energy resources and does not produce waste products or release carbon dioxide into the atmosphere. For instance, the solar energy is the energy from the sun which can be used to produce electricity and heat. Similarly wind and thermal energy from inside the earth can be used to produce different types of energy. However most of our energy demand is met by energy produced from non renewable energy resources such as the fossil fuels like coal, oil, natural gas. These energy resources have been formed over million of years by the action of the pressure from soil and rock on the remains of dead animals and plants and the heat from the Earth’s core. These energy resources release waste product and carbon dioxide into the atmosphere.

Energy is required to perform almost all the tasks. The non renewable energy resources are fast depleting. These energy resources should be used smartly and the government must encourage the use of alternative renewable energy resources. It provides a great alternative to the energy requirements of the people and is also environment friendly.

A new hydro power technology is being developed by Sarfraz Ahmad Khan of Pakistan. In theory these hydro plants would not require a reservoir and would have a minimal impact on the environment. They could be run side-by-side in rows and would be much cheaper to build, operate and maintain. Sarfraz has high hopes that his ideas could revolutionize hydro power in his country and across the globe.

Many of the models of calculators are an auto turn off; one who is working has to keep the calculator non-operating for a few seconds to turn it off, and some can be switched off by closing their lid. Some of the calculators are provided with the power off button. The displays of Calculators are liquid crystal displays. Some of the modern calculators are provided with memory cards and make the calculator able to store data. The storage capacity can be increased by putting the memory cards with large storage space. Initially many of the schools allowed their students to use calculators for solving their mathematical problems but many of the parents and teachers opposed this idea of allowing calculator in schools because they thought that the students will then totally rely on calculators. There was an agreement made that the students will be allowed to use the calculators only after when they attain proficiency in solving the sums themselves. After a brief research it was proved that calculator restrict the mathematical thinking power of the children’s and lack mathematical problem solving skills.
