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 »


Competitiveness of oil, coal and renewable energy sources

The power of Nature

The International Energy Agency (IEA) released its annual Medium-Term Coal Market Report where was clear that coal’s weight in the global energy mix continues to rise. The IEA expects that coal demand will increase in every region except in the US, where coal is being pushed out by natural gas.

After all the conferences, international agreements, plans and strategies regarding the implementation of renewable energy, most analysts are still talking about competitiveness of these resources. It is still the money that is put on focus of most of the reports but not the simple fact that life is on stake. Life was not created by money though it could be ruined by the same.

There is a Bible comparison that flashes through mind – The Plagues of Egypt and especially the Plague of locusts: “They will devour what little you have left after the hail, including every tree that is growing in your fields.“

Like a swarm of locusts the human race is trying to swallow what has left from billions of years of evolution in just few generations, leaded by the devastating greed.

When we’re talking about competitiveness of renewable energy sources, we’re talking about strength but we forget that the water drop will destroy the stone. We close our eyes for this simple truth because our time is limited. There is no place for parallels between fossils and renewable energy sources as there is no way eternity to compete with hours.
