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 God of Sun – energy for renewable life

Sun is our life

Christianity, Islam, Hinduism, Buddhism and other religions are systems of beliefs and values that determine the behavior of human beings on the planet but although almost all of the religions are based on eternity, none of them have ever been a reason for avoiding death. We are supposed to deal with life while Gods will take care after death.

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.

A matter of energy, matter and energy or just time.

Earth, wind and clouds.

To create something, you need energy and lot of time – to destroy you need seconds and in some cases you don’t need power as for destruction you can use the one accumulated in the system you intend to destroy. Having in mind that many people are scared of so called “Mayan apocalypse” – the conclusion of the 5,125-year “Long Count” Mayan calendar, it is strange why there aren’t such worries about “Industrial apocalypse”?

Fossils or alternative of life

Dinosaurs existed for more than ten millions of years

A mysterious fossil specimen that has been in London’s Natural History Museum for decades has been identified as most likely coming from a dinosaur that lived about 245 million years ago – 10 to 15 million years earlier than any previously discovered examples.
The researchers believe the creature named Nyasasaurus probably was about the size of a Labrador dog.
