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 »

Resource wars in the era of renewables

Our energy needs are just dust

Renewable energy sources are slowly pushing away the dependence on traditional energy. Each and every day we break the chains of our reliance on limited in quantity resources. Each and every day the technology improves and we gain more and more energy from the nature without destroying it.

Modern slavery

Renewable energy could brake the grid chains

Slaves were chained together so that if one tried to escape, it would not be as easy. He would need the whole group to escape with him. And it would be very slow. Slaves power was needed. Today we need energy for the machines that have taken the place of the “live force” – animal & human. But it seems that all of us are chained by the invisible and mighty chain called “grid” and “stations”.

The energy of cash

Does energy controls money or not

In physics, energy is understood as the ability of a physical system to do work on other physical systems but despite of such explanations there is no complete understanding of what energy is.
According to the law of conservation of energy, energy can neither be created nor destroyed by itself. It can only be transformed.

We often use power as a synonym of energy. Power is not a complete synonym but mostly refers to the conversion rate regarding the above mentioned law.

Giant or dwarf

Sun powers life

Some will state that the size always matters while others will count on the effectiveness. Let us take a look at the renewable energy sources. Of course not all territories could benefit from the power of the water as not all have this valuable resource while the sun and wind are for everybody.
