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 »

Join the army of renewable power if you cannot beat it!

Wind could fight the oil

Few decades ago, renewable energy was in the middle of many local fights. Bespattered, rejected and neglected, the cause found political support and the war with the fossils became a World War.
The most valuable asset in any war is time and as Sun Tzu has wrote, several centuries ago, in “The Art of War”: “If you sit by the river long enough, you will see the body of your enemy float by”.

Renewable energy exploration – economical wonders

Ships powered by oil

Renewable energy sources were doubted. Renewable energy was subsidized. Technology was blamed as unreliable. The Earth was flat and the stakes were burning.
But now it seems that there are believers. Believers in the power of the sun, wind, water. A power that could not be measured. And these believers support the technology and exploration of these resources. For less than a decade, their efforts have made the solar technology four times cheaper, while in the same time the prices of the fossils were going up. What would a reasonable man prefer as an investment?

Renewables vs fossils or credit vs savings

Flowers and trees are one of the simpliest forms of energy

Renewable energy sources or fossils? The Earth is our home. The human race is one big family despite the fact that many of the cousins (nations) do not know each other well and communicate hard. We share one heritage though our mother Gaia hasn’t divided her share equally. It is always like that with mothers – they favorite some more than the others, but they love all of their children. Our father Uranus, on the other hand, treated us evenly by letting light and wind to all. We’ve grown up know, so we must take care of our own future.
