Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight‚ wind‚ rain‚ tides‚ waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation‚ hot water/space heating‚ motor fuels‚ and rural (off-grid) energy services. About 16% of global final energy consumption presently comes from renewable resources‚ with 10% of all energy from traditional biomass‚ mainly

portrayed in the poem‚ Overall it is the poet asking the wind to scatter his words throughout the world Asking the wind to hear him First three cantos - decribtion of the powers of the wind First Canto Explains the purpose of the wind during the seasons Shows that the ode to the wind is not only optimistic. Dark element(leaves dead‚ Ghosts) The wind is considered the destroyer because of the way it sweeps life from the trees The wind id considered the preserver because it helps spark spring

The Colorado River Threats to river and delta: Water flow is decreasing. This water serves 30 million people in seven U.S. states and Mexico‚ with 70 percent of its water siphoned off to irrigate 3.5 million acres of cropland. Possible actions between the United States and Mexico could significantly reduce the flow of water into the delta‚ increase its salinity‚ and alter the natural vegetation. Drought has lowered water levels in upstream reservoirs‚ eliminating the occasional floods the delta

Alternative Energy Sources Fossil fuels will not last forever. If the human race wishes to continue to live the way we do‚ then we have to look at alternative energy sources such as: geothermal‚ nuclear‚ solar‚ wind‚ and hydroelectric energy. Alternative energy sources are not without faults‚ but along with faults‚ there are benefits and solutions to the issues. Geothermal energy is a well-proven energy resource that can be used to provide both heat and electricity. Geothermal energy is very predictable

How does my wind generator work? Every wind generator‚ whether they produce enough energy to power a city or to power a small radio‚ works on these same basic principles... 1. The wind blows 2. The generator’s vane (tail) causes it to turn into the wind 3. Blades attached to an alternator/generator experience the force of lift and begin to spin 4. The spinning creates electricity for us to use directly or to charge batteries Sounds pretty simple eh? Well‚ then how the heck do I build one

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

on Green Energy and the affect of economy on it. The use of renewable energy is on the rise around the world. The costs of this renewable energy is relatively costly. This means in the long run over time the costs will be paid for and consumers will see a lower energy bill. There has been great achievements in smaller countries with the introduction of green energy. They have seen how useful this is and the way it provides electricity with no problems. Many countries rely on wind power energy

The Tides Intro The location I chose for this project is the Charles River in Boston Massachusetts. The Charles River had been referred to as one of the dirtiest rivers in the US throughout history due to the Watertown Arsenal that had been full of gunpowder as well as other artilleries and firearms. The Charles River had also been used for the much of America’s hydropower with its dam. The Charles River had been used in the hit Boston based band‚ Dropkick Murphy’s song‚ “Dirty Water”

“Ode to the West Wind” Theme: - Man and the Natural World Nature itself is more powerful than man but we are part of the natural world therefore man and the natural world is connected. We need to take care of nature as we take care of ourselves for nature is more powerful so then it can strike back to us like the west wind. The west wind represents the period of winter but we know that winter is always followed by spring. Spring symbolizes rebirth‚ life and growth. So we humans
