Time to Act on Global Sustainability - Essay ExampleConsumption of these resources has now reached their peak. Huberts curve of oil production, a natural finite resource, shows that mans peak consumption and production of oil will be from years 2005 to 2010. After which it will decline at an exponential locate meaning that oil, which is as scientists calculated, used in about 500,000 different processes, will be finished. Can you even imagine a world without oil in it Look around you and try to spot anything which has not used oil in its production. You wont be able to because even if you see one thing in your room, you still used your car to go get it from the store didnt you Get my pointThis has actually created quite a stir in the world. People be actually predicting a third world ending in destruction of the earth as a result. But being students and having minds to think of creative solutions kinda of brooding over our problems, there might actually be a way out. The best way to replace Mother record is Mother Nature In other words, we need more Sustainable Resources. Let me explain. Oil other important resources that we are using presently are all finite. This centre finding resources which are renewable and recyclable. The best thing is that we already use these resources, even if they are in a minute amount. So the primary look is already taken care of. Sustainable resources are those which keep on going and dont run out. A very simple example is of a forest. If you caterpillar track a tree, it will grow back in time. The forest then, has sustained itself. The key to this idea is to use these resources in a manner that they are not over consumed (used faster than they can be replaced naturally). Optimum consumption of these resources is the maximum use they can be put to, where the consumption rate is equate to the replenishment rate. There are several types of sustainable resourcesHydro PowerThis is officially the largest source of renewable en ergy. Currently there is a production of 77,000 megawatts by this resource which is equal to providing 35 million homes with energy. It works by converting the flowing water into electrical energy with the use of turbines. Although it does not create any sort of pollution, it can wrong aquatic life and displace dry landscapes. So its not completely a guilt free way of producing power.Bio EnergyAs the name suggests, it is created by perfect life decomposing. This source produces about 7000 megawatts of electricity of the world. This too produces sulphur dioxide gas but les of it in comparison with coal.Geo thermal EnergyGeo means earth and thermal translates to heat. This adds up to mean that geo thermal energy utilizes the steam and hot water found near the earths core and turns it into electricity with the use of turbines. The only issue with this is that land sites with such a unique feature are very rare and setting up the plant is very pricey. However, it still produces abou t 2800 megawatts of energy annually. flatus EnergyThis produces about 2500 megawatts of energy. It works on the principle of a windmill. Simply put, wind rotates the blades which powers up a generator. The main disadvantages of this resource include very expensive machinery, hazardous for birds and unreliability of the wind because its not present throughout the year.Solar Energy, photo voltaic cellsThese cells harness energy from sunlight by freeing electrons from equivocal atoms in the
