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 »


The North Star – Renewable energy future guide

The old and heavy alectricity construcions

When wind energy was used as a main power to explore the world, there was a guiding light to those who sailed across the oceans – the Northern star; never changing position and showing the right direction. Now we have enough technology to find a pin in the desert and that’s why we’ve probably have lost our connection with the guiding light of the stars.

Today, there is a reason to look to the north. Not above but amongst us. To see the guiding light of a community that was not tolerated by the nature as the southern nations were, and probably that’s why has developed an energy intensive economy.

Sweden, the country that already has one of the lowest-carbon economies among OECD countries has set ambitious goals. And they will achieve them with deeds but not with declarations and leads. According to IEA, today, Sweden’s electricity supply is almost completely carbon-free, and the country has a very low share of fossil fuels in its energy mix thanks to strong energy and CO2 taxation in the sectors not covered by the EU carbon market. Sweden has opted to allow for the replacement of its existing nuclear reactors at the end of their lifetime.

In a joint market with Norway, Sweden is steadily increasing the renewable energy supply to consumers, lowering the costs through a renewable electricity certificate system.

May be it is time to look to the North in search of our guiding light.
