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

Negative and Positive Ecological Impacts of Technology Introduction In today ’s society more people are working longer hours and utilizing more technology in their everyday life. As a result of these longer hours and increased use of technology‚ more energy is being consumed. (Hayden and Shandra 575) The impact that this is having on the environment is substantial in both negative and positive ways. It is hard to deny the benefits modern technology has produced for the world‚ in industry and in everyday

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Geothermal energy What is geothermal energy‚ and how can we use it in society? Geothermal energy is the use of the Earths very own energy. It’s renewable‚ clean and can range to easily acquirable hot springs on the surface or hot rock found a few miles below the surface. Or you can go a bit deeper and hit the extremities of the molten rock (magma). In the US around 80% of all geothermal hotspots are found on the western states i.e. Alaska and Hawaii. Wells are drilled deep into the underground

Topic Canada should subsidize renewable energy options such as wind and solar power in order to increase the share of renewables in Canada’s energy balance. Introduction Canada government subsidizes a number of socially beneficial services‚ including health care‚ education and energy services. Subsidies to the energy sector mainly are for oil and gas production‚ however‚ they are not all socially beneficial[figure 1]. In fact‚ they have negative impact for the environment and hinder

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy
