Learn About Different Types of Renewable Energies
May 2, 2016
There are five main types of renewable energies: solar power, wind energy, hydropower, biomass and geothermal. Their common characteristic is not to produce emissions (or little), and thus, help fight against the greenhouse effect.
The photovoltaic or solar thermal
The sunlight produces solar energy. We distinguish photovoltaic energy which is obtained directly from the radiation, solar thermal power that uses the heat from the radiation.
The air initially wind energy
The ancestors of the windmills are windmills. Wind turbines produce energy, electricity for example, from the movement of air masses.
Hydropower thanks to ocean currents
Hydropower is obtained directly by water, either from tides and ocean currents, waves, the encounter of freshwater and saltwater. The ocean thermal energy, which comes from the temperature difference between deep water and surface water is also used.
The energy biomass from organic matter
Energy Biomass includes wood, biofuels (derived from plants such as rapeseed or sugar beet) or biogas. This energy is produced by burning or metabolization of organic material.
Draw energy from the ground, geothermal
Geothermal energy is a renewable energy from the extraction of the energy contained in the soil. It can be used for heating, but also for the production of electricity. This is one of the only power not dependent on atmospheric conditions.
Introduction to renewable energy
April 19, 2016
The wind, rivers, lakes, oceans or even the heat deep in the earth is renewable energy. Modern technology has begun to exploit these infinite sources of power by converting them in the electricity, transport fuels and the heating our homes and of the water. They have the potential to completely replace the conventional fuels. It is scientifically proven that the use of conventional fuels is the main cause of climate change. In spite of what justifies the cost of a new infrastructure is a source of heated debates. People are creatures of habit and they are resistant to change, even when it is in their best interest. Now is the time of the action with the certainty that we are doing the right thing. That all those who would like to sow the seeds of doubt be reprimanded with the facts.
Using the power of the moving water to generate electricity is renewable energy.
Hydroelectric dams are a form of renewable energy, we are all familiar with. The new technology is developed to produce the electricity from tidal and wave. This will create the potential of 12.380 miles of coastline U.S selectively be put to advantage of the creation of a new block of power. This is a constant movement reliable which can help to solve our energy problems. It is renewable energy in pure form. The cycles of the water here on the planet earth were in movement well before the man and will continue indefinitely.
The kinetic energy of the air in motion or wind energy is also renewable energy in pure form. It has been used for thousands of years in the form of sailboats and windmills. Now, in modern times, it is used to produce electricity. Wind energy is directly affected by the topography of the terrain. The summits of the Smooth, rounded hills, plains open, the shorelines, or gaps in mountain which channel the wind are the best places for wind farms. Offshore is also excellent due to the best wind speeds. Wind energy alone has the potential to meet total world demand 30 times.
It is common 24 hours and not intermittent as other forms of renewable energy. The majority of the American continent has a 100 degrees Celsius below. The western part of the country has large surfaces of 200 degrees Celsius, apparently due to its sitting on the Ring of Fire of the Pacific. Enhanced Geothermal Systems are a more recent technology which could benefit from this huge source of energy. The geothermal heat has the potential to meet the global demand total of 1.5 times. As the technology to extract it improves its potential will increase.
The radiant heat and light from the solar energy or solar energy is another huge source of renewable energy. It is the source of energy which creates four other forms of renewable energy. The wind is caused by atmospheric convection that is fed by the sun. The ocean waves are caused by the wind. Rivers are formed by precipitation caused by evaporation of the water due to the heat of the sun. All green things and growth depend on the energy of sunlight and are biomass, we use as fuel. Solar energy has the potential to meet total world demand 4000 times.
Solar energy is more known under the form of solar panels, but this is a single form. There are two categories of solar technologies. Passive Solar is designs that do not require other energies. The solar architecture, green roofs, and the solar chimneys are examples of the passive solar energy. Solar Energy Solar converted assets in other forms of energy, normally the heat and electricity. Photovoltaics and solar energy concentrated are examples of active solar energy. The variety of ways to use this energy source renewed
