Solar Energy Fire Hazards Since most solar collectors basically concentrate the sunlight that they are able to collect from the sun, it can be a fire hazard, especially since fire can very easily start if there were very high concentrations and levels of solar energy. These high and dangerous levels of solar concentrations could easily ignite combustible materials, making it a possible hire hazard on any home. The solar energy supply will be available as long as the sun is existing. On the other side, oil is not considered as a renewable source of energy. Oil can take millions of years to form. At present, oil reserves are being depleted at a very fast rate compared to its time of development. People will have to prepare for the consequences of running out of this resource. However, there are still a lot of things that people do not know or fully understand about solar energy just yet, like what it is exactly, and how to use it to its utmost potential. In order for you to fully understand more about solar and sustainable energy, and what the future holds for it, you need to learn more about the history of solar energy. Alternative sources of power and energy will not only help you avoid burning fossil fuel to help provide electricity for your home, but will also help you save a considerable amount of money on the cost of your utility. One of those alternative energy sources is solar energy. There are actually a number of different solar energy systems that are available in the market today. Make sure that you do not touch it directly. Use tongs to position the copper on the hot plate. Switch the hotplate on as warm and hot as possible. Cook the copper using red hot heats for about 30 minutes. Use a thick black layer of oxides and allow to form at the surface of the copper. Be sure that you do not leave the copper unattended while you are cooking. You will observe that the colors change as the copper starts to oxidize, and gently transform to black. Let the copper stay on the burner for about 40 minutes or up to the time that a thick coat of oxidized black material turns up. Turn the heat off on the burner, then let the copper cool in the air.
