Coal is an un-renewable fossil fuel which is known as a cheap and reliable energy source. It has many environmental impacts‚ both positive and negative. Coal has a great economical effect providing thousands of people with jobs‚ and harmfully leaving individuals with un-producible land. It has a social impact negatively when people live near coal mines. Coal is a flammable‚ mostly black rock‚ which has been located in 50 different countries around the world. Coal is known as a fossil fuel because

Effects of Pollution 1. Environment Degradation : Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus‚ preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species. 2. Human Health : The decrease in quality

Solar Energy Solar energy in one form or another is the source of nearly all energy on the earth. Humans‚ like all other animals and plants‚ rely on the sun for warmth and food. However‚ people also harness the sun’s energy in many other different ways. For example‚ fossil fuels‚ plant matter from a past geological age‚ is used for transportation and electricity generation and is essentially just stored solar energy from millions of years ago. Similarly‚ biomass converts the sun’s energy into a

Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface‚ and even farther down to the extremely hot molten rock called magma. These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly

are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when it is built. These tunnels are lined with turbines

Energy Systems Assignment By Thysje Fartlek Training Before we started the fartlek training‚ our bodies were using the aerobic system and bi-products of this system are carbon dioxide (CO2) and water (H2O). Our heart rate (HR) was low‚ 60-70 beats a minute‚ and our breathing rate (BR) was slow and deep‚ 1 breathe about every 6 seconds. The demand for fuel was low because we didn’t need to supply the muscles in our body quickly. Once we started walking‚ the demand for fuel increased but only
