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 »

 

Time and energy – dust in the wind

Nature and wind

Time – a dimension, measuring past, present and future, a dimension that determines our existence, firmly connected with all of our countable wealth and heart of all our emotions as it separates them, is something that is not so often put as an argument in energy disputes. Analysts, manufacturers, decision makers, governments are talking mostly about money and funds but not time. There is a lovely quote from Kansas’ song that comes to mind when thinking about this:
“I close my eyes, only for a moment, and the moment’s gone
All my dreams pass before my eyes, a curiosity…

Same old song, just a drop of water in an endless sea
All we do crumbles to the ground though we refuse to see …

Now, don’t hang on, nothing lasts forever but the earth and sky
It slips away, and all your money won’t another minute buy
Dust in the wind
All we are is dust in the wind …”
We often talk about renewable energy systems as function of the investment cost and the efficiency, assuming some accounting parameters such as cost of capital and depreciation period, but we hardly assume that investment cost is a dust while life and knowledge are rocks. The question “what is energy?” is difficult to answer, but it is clear that energy is always an indispensable prerequisite for performing mechanical work. Life was not created or supported by money; energy and knowledge were transferred without investment cost for thousands of years, raising the efficiency of one’s labor and his added value to the society.
Focusing on time will set us free from colored papers and let us search the way to harmonize our lives with earth, wind and sky.
