Solar energy sources

PV solar power - Era-Energy has started to present local, national and global companies developing, exploring and promoting renewable energy sources. More »

The Earth energy and the beauty

The Earth energy sources - Earth’s energy comes from the original formation of the planet and from radioactive decay of minerals. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.

The power of the water

Hydropower, hydroelectric power or water power is power that is derived from the force or energy of flowing or falling water, which may be harnessed for useful purposes. More »

The power of the wind

The wind power is the ability of air movement to do work. Today, wind energy turbines are used mainly for production of electricity. It is a clean and renewable energy source that can produce enough electricity to power huge areas. More »

The invisible power

The energy of the wind is invisible and so powerful that has allowed humans to exploit the surface of the planet long before the discovering of electricity. More »

Energy from the sun

Renewable energy

Renewable energy sources are one of our ways to preserve life – life as a symbiotic connection of all biological forms and as a self-reproducing beauty. It is our obligation to protect the Earth as mother of our life.

Renewable or alternative energy sources are just one small step in this direction. Now we have the knowledge and technology to support our community with less damage caused to the body of the planet that will feed our children and grandchildren the same way as it has done it for all creatures since the beginning.

Geothermal power – from the thermal energy generated and stored in the Earth, Hydropower or water power, Solar power or energy from the sun and Wind power are forces that were worshiped as God’s ones in ancient times and they are the heart of the alternative green energy that we can use as defender of our system.

Here, on Era-Energy, you will find a lot of useful information regarding these types of energy sources – from basic info and equipment manufacturers, through consultants, developers and installers, to the associations, governing and regulatory bodies.

What is a renewable energy? It is the one that comes from natural resources such as sunlight, wind, water, geothermal heat. They are pollution-free and inexhaustible. Each day these resources are forming more and more of the global energy consumption.

WIND POWER

Wind on our planet is the movement of air caused by the unequal heating of large zones of Earth’s surface by the sun. Today, wind energy is mainly used for the production of electricity. It is a clean and renewable energy source that can produce enough electricity to supply millions of homes and facilities.




SOLAR POWER

Every second the Sun produces more power than the one mankind has consumed from the dawn of history, and it has been doing that for billions of years. The energy that comes from the sun is called solar energy. It is a clean energy source that can be used. It existed when the coal and gas were formed, when the man was born and though we use it in many different ways, there is still more to learn about the main source of power that we have.

People have used solar energy for thousands of years and, as the Sun is the foundation of our existence and the largest power-plant for our needs, we can try to raise the efficiency.

HYDROPOWER

Hydropower or water power is power that comes from the force or energy of flowing or falling water, which may be harnessed for useful purposes. Since ancient times, hydropower has been used for irrigation and as main operational force of various mechanical devices, such as watermills, sawmills, textile mills, cranes, and lifts. It is the most widely used form of renewable energy.

GEOTHERMAL POWER

Geothermal energy is the energy generated and stored in the Earth. Thermal energy is the one that determines the temperature of matter. Earth’s energy comes from the original formation of the planet.  The word geothermal originates from the Greek roots “geo”- earth and “thermos” – heat. Gaia was the great mother of all.

If you want to be a part of this changing world, if you want to help The Earth to survive or just to be independent you can make your choice now. Here are listed most of the equipment manufacturers, decision makers, developers and organizations within the industry range.

LIFE IS THE ONLY ENERGY SOURCE THAT MATTERS

Renewable solar energy

The Sun produces a lot of light every second and it has been doing that for billions of years. Energy from the sun is called solar energy. Renewable solar energy is a resource that is inexhaustible and readily available, unlike fossil fuels such as coal, oil and natural gas. It is a clean energy source that can be used pollution free and allows for local energy independence.

People have used this power for thousands of years. Houses have windows so that sunlight can get inside and provide heat and light. The sun’s energy can also be used to heat water and even food. If you own a magnifying glass, your parents have probably warned you about leaving it in the sun. Solar energy can actually make the magnifying glass burn objects underneath it, causing a fire. This type of energy from the sun in the form of heat is called solar thermal energy. We can also turn the sun’s light into electricity. This is done with solar panels. Solar panels are made up of a material called silicon. The silicon is heated and formed into very thin wafers. When the sunlight hits the solar panel, the electrons (tiny particles) in the silicon move and flow through wires built into the panel.

Types of solar energy

Solar power is used a number of different ways, of course. There are two very basic kinds by the type of energy it is converted into:

– Solar thermal energy collects the sun’s warmth through one of two means: in water or in an anti-freeze (glycol) mixture.

– Photovoltaic solar power – converting solar energy into electricity using photovoltaic cells.

History of solar power

The Romans took their knowledge of the sun being a source of energy as they were the first people to use glass windows to trap the warmth of the sun in their homes. They were so serious about the preservation of this solar energy that they erected glass houses to create the right conditions to grow plants and seeds.

While many people were benefiting from solar power it wasn’t until 1776 that the first solar collector was built. This collector was built by a man named Horace de Saussare. His collector was cone shaped and would boil ammonia that would then perform like refrigeration and locomotion. This first solar power collector attracted much interest in the scientific community through the 19th century.
