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 »

 

Renewable energy sources – foundations of life

The energy of life and death

When we use renewable sources of energy, we should ask ourselves: What is the connection between these sources and our existence? Life is the biggest miracle on our planet and its foundations are clear.

We could survive without oil, coal, gas and someday we should learn how to do it as they are limited, but life on our planet will come to an end if we do not have the heat and light from the sun, the air we breathe and the water. We are part of the biomass as well as our food is and, of course, the Earth is our cradle, our home, everything we have.

So, as life and energy are tight together, we should consider whether we need to be greedy about providing comfort through energy sources that we can’t regain or rely on the foundations that nature has set.
