In nowadays context it is very important to use the alternative source of energy as the natural resources of the Earth seem not to be enough for our generation. It have thus been implemented renewable energy projectsthat use natural resources.
The concept of “solar energy” refers to energy that is directly caused by the transfer of light energy radiated by the sun. This can be used to generate electricity or to heat the air inside of building. Although solar energy is renewable and easy to produce, the main problem is that the sun does not provide constant energy in any place on Earth.
In addition, due to Earth’s rotation on its axis, and thus the alternation of day and night, sunlight can be used to generate electricity only for a limited time each day. Another limitation of using this type of energy is the existence of cloudy days when solar energy capture potential decreases due to shielding sun sensitive, limiting the application of this form of renewable energy technologies.
Solar installations are of 2 types: thermal and photovoltaic. The photovoltaic produce free electricity. The heat helps to save gas at a rate of 75 % per year. A house that is available both solar installations photovoltaic panels and thermal vacuum) is considered “without an invoice” batteries as the energy accumulated day is sent to the network ). Solar works even when the sky is cloudy. They are also resistant to hail ( in the case of the best panels).
3. Hydraulics Energy;
Hydropower is the capacity of a physical system (water) to perform mechanical work on the transition from one state to another state time (flow). Because the water cycle is maintained by the Sun’s energy is considered a form of renewable energy.
Hydropower is actually a mechanical energy, potential energy of water formed on the level difference between the lake and the central question of the kinetic energy of moving water.
Exploiting this energy is hydroelectric power in that turn potential energy into kinetic energy of water, which then captures using hydraulic turbines that drive electric generators into electricity.
All types of hydraulic energy is considered kinetic energy of waves and tides, and osmotic potential energy.

The future relies on solar energy
Solar energy has become one of the most desirable sources of power these days because of ecological and economical reasons. It has been in existence since the beginning of time and it is used by microbes, plants and animals as a primary energy supply in life. Plants use photosynthesis and contribute to the creation of nearly all the food on Earth which is the base of the food chain. The fossil fuels we rely on in the present are the product of plants and animals which have lived a long time ago.
Considering its potential, humans have started to harvest this type of energy and have started to invest into technology which can convert solar energy to electrical energy which could transform a city of today into a solar city. Annually the Earth’s atmosphere absorbs about 3.85 exajoules of energy from the sun. The use of electricity worldwide is about 56.7 exajoules per year. This shows the great potential of making value from the energy sources the nature provides us with.
Solar energy can be captured through solar panels placed on households or businesses or with the help of more advanced systems developed by large power plants with the aim of converting a larger mass of energy than the small home panels can provide.
The advantage of using solar city as an alternative power source is consisted in the great effect is has upon the environment. No CO2 dejected, it helps you cut down the reliance on fossil fuels. The main concern people have when thinking about converting to using solar energy in their homes is the worry that it will cost considerably more to install such solar panels on their roofs. However since the technology is evolving every day, you needn’t worry because there are a lot of methods which can cut down your costs: you can benefit from tax reduction, or reduce the price of installing solar systems up to 30% if you make an official claim. All you need to do is document yourself about the procedure and make up you mind to be the first among your neighbors who think big and smart.

Converting to solar power – try it out first
Renewable energy have in common the fact that they are generally free of any pollutants, they harm the environment less than common energy sources and the systems which use renewable energy are less costly to operate than those that use fossil fuels. The best type of renewable energy which has all these characteristics is solar power. Solar power can be a bit costly to acquire and install but if you have a tight budget but still wish to start using this type of energy you can make an experiment, for example make a lighting system or you can experiment with a hot water project using solar energy.
For the lighting system, the first step is to purchase a small DC power lighting system which is easy to set up. If you don’t wish to set it up yourself you have the option of buying a DC lighting system complete with a solar panel which provides enough power for a small lighting system or a DC appliance. You also have the option of photovoltaic cells, charge regulators, inverters etc the choice is yours for the pieces which form your experimented solar energy system. With this you can light outdoor landscapes, gardens, walkways, driveways, patios, pool areas etc.
If you want to test how solar power works you can also try doing this by heating water. To heat water through solar power you need to use solar heat collector panels which have pipes included in the frame that capture the heat from the sun via a water alcohol mixture contained in the pipes. The mixture carries the captured heat to a heat exchanging device which will heat the water you use in your hot water system.
If these two experiments finish by satisfying your curiosity about solar energy you can proceed to turning to a bigger system which can supply you with a larger amount of solar energy to be converted to electrical energy or used for heating the water project you use in your household.
