Solar panels and wind turbines take the lion\u2019s share of the DIY alternative energy market, but depending on your environmental conditions you may consider a hydroelectric generator as well. Ready-made applications are notoriously expensive to start with, even though they are worth every cent and pay themselves off in the long run.<\/p>\n
For most people, these start-up costs are a major hurdle in freeing themselves from the tyranny of the grid. However, DIY alternative energy devices<\/strong> can slash thousands off your investment budget and help you cut down or even eliminate your electricity bills<\/strong>.<\/p>\n Here below you will find information on the 3 main options: solar energy, wind energy, and hydroelectric energy.<\/p>\n Solar energy<\/strong> is the most popular type of alternative energy for household electricity and is obtained thanks to several sets of\u00a0photovoltaic cells<\/strong>\u00a0making up solar panels<\/strong> to convert the light from the sun into electricity through a phenomenon called the photoelectric effect. The\u00a0photoelectric effect consists of the release of electrons from a surface once it is struck by light.<\/p>\n Light itself can be viewed as a stream of particles called photons. Each electron needs a photon to be released from the surface, providing that the frequency of light is sufficiently short, as in the case of visible or ultraviolet light. If the frequency is too high, the light might be of high intensity but still not able to produce the photoelectric effect, with no electrons being released. For the photoelectric effect to occur, a photon must be energetic enough to release an electron from the surface. Therefore, it is the frequency of the light<\/strong> the key element for the photoelectric effect to take place. Without a sufficiently short frequency, all intensity in the world will not cause the photons to release electrons.<\/p>\n Photovoltaic energy<\/strong> is the most common and viable way to get homemade free electricity (free apart from the installation costs) as it has become relatively easy and very cheap to implement a DIY project. More and more people are resorting to homemade solar panels<\/strong> to offset the high purchasing costs associated with ready-made solutions, often in the range of $20.000 for an average household, while a Diy solar panel<\/strong> could be assembled from parts found online or at local hardware for as little as $200 and some spare time. Next, you can find a detailed blueprint for\u00a0DIY solar energy projects, the most common household alternative energy.<\/p>\n Wind power<\/strong> is the second most common household alternative energy available, it is easy to implement and is often used as a complementary source of electricity to solar power. This is because these two sources of renewable energy are intermittent, depending on day time or season, making them both useful when the other is unproductive. However, depending on geographical location and local climate, just one of the two technologies will be suitable for all household electricity supply.<\/p>\n Wind electricity is generated via vertical or horizontal axis wind turbines<\/strong>. The most common type is the horizontal axis turbine, both for commercial applications and households. For a common household, it is better first to calculate how much wind is available to work out how many turbines are necessary. For this, you need to assess the wind power density of your location, which is the annual power available per square meter turbine, calculated at different heights.<\/p>\n It is also better to build several smaller wind turbines than a single big one because of the extra costs involved in erecting a large supporting mast, both for materials and working crew. Most modern turbines<\/strong> have a 3 blades design because this has turned out to be the most efficient, and have them placed upwind, in front of the mast, so that the turbulence generated by it does not interfere with the blades, making the turbine more efficient.<\/p>\n Wind turbines work by converting wind energy into electricity. Traditional horizontal axis turbines are made up of 3 main parts.<\/p>\n Wind power is the second most common source of homemade alternative energy and is particularly suitable if you live in a windy location, such as near the sea. It can be easily implemented with a\u00a0DIY wind energy project, helping to cut down electricity bills in a very green way.<\/p>\n From a commercial and statistic standpoint, hydroelectric power<\/strong> is by far the most successful of all the renewable energies available, accounting for 88% of all alternative energy produced in the world<\/strong>. Hydroelectric power stations are the norm to supply electricity grids. However, for a single household electricity needs, hydroelectric energy should be considered as a complementary source of energy to solar and wind powers.<\/p>\n This is because micro-hydroelectric generators<\/strong> such as DIY homemade devices<\/strong> do not come with reservoirs at different elevations to store energy like the big power stations. Reservoirs are in place to store energy when demand is low and release it later when there is an upsurge. Because of their intrinsic simplicity, they provide an intermittent supply of energy that fluctuates with the seasons and water flow.<\/p>\nDiy Alternative Energy From The Sun<\/h2>\n
