How many films with post-apocalyptic themes you've seen in the opening image in which we see a world famous city in the mist of smog, with big and scary industrial chimneys and gray vapor rises everywhere. This hypothetical scenario could become a reality not only in industrial zones but everywhere we turn.

 The energy needs of the world are increasing daily and the situation in which we rely on the energy potential of fossil fuels such as coal, oil or gas is completely unsustainable. The speed at which the oil is consumed is totally absurd. It makes a great piece of the pie of fossil fuels, but for every barrel of oil that is found we consumed 8.

 During the industrial revolution escalates the use of fossil fuels as drivers of change. It was needed one  significant and uncontrolled growth and development of the industry, and when we mature and are responsible as a society it is time to take responsibility for our  actions and explore alternative ways of obtaining energy.
 It is a green energy that we are talking about. It actually has nothing alternative, it is the most natural way to generate energy. The green energy includes all renewable energy sources.

 These are the ones that cannot be exhausted and provide clean energy without harmful effects on the environment and our health. Wind, water and sun are mostly drivers of this, not so new ways of using energy.

 All renewable energy sources are somehow indirectly connected with solar radiation. Our Sun sends to  Earth  15,000 times more energy than it needs, so we just need to know how to use it and transform it  in the  forms of energy that are necessary for us.

 Panic about the energy crisis has forced many governments and communities of countries like the EU to work on their energy plan and increase the percentage of energy that comes from renewable sources.

 Although excuses for poor utilization of green energy were that thus can not produce a sufficient amount of energy needed for today's society, for example, the energy potential of wind energy is five times larger than today's total energy production so such claims are completely unfounded.

 In this post are shown some information about solar power and energy efficiency in our houses.

 Almost every heating period starts with the raised amount of electrical and thermal energy. 

 Besides these boosts, we are threatened of enhanced costs of gas and also petrol. Energy producers and distributors say the price increase is justified, and people and the state in the event of gas state that this price elevate is unjustified.

 But exactly what absolutely everyone should know is the fact that the price of electrical power will continue to increase. In addition, the price of other energy sources (oil, gas, wood, briquettes, pellets ...) is going to have tendency of growth. That is a very simple fact so we must all pay attention to this.

 We as citizens don’t have sufficient great power to cut back or freeze energy prices, however we can adopt, concretely to be energy efficient. As we all already know, energy-efficient can mean to decrease energy consumption, but with no need to reduce our standard or comfort of living.

 Reported by some studies 35-45% of the energy is spent on heating and cooling of residential home. 25 -35% of wasted electrical power is eaten by home-based appliances. Television and computer have energy consumption by 10-20%. Heating of water for sanitary needs in the house varies somewhere between 5-20%. Lighting home again approximately eats 8-12% of electrical energy.
 
 If we isolated our residence and we would mount better home windows the intake of energy for heating and cooling would be reduced a lot. With the purchase of household devices with high efficient use of energy, their power consumption is decreased pretty much. If I shut down the TV when coming out of a room or the desktop immediately after each use, will also decrease the energy consumed. If you change old lights with unique LED lights, lighting electricity expenditure is likely to be reduced by 80%, and even if high quality solar cells for water heating the charge for heating water will surely be close to 0 all year long.

 Especially remarkable are the outcomes of using solar energy as:

-Hot water throughout every season: the system works well all year round, but according to the sunny days, there's a possibility that the water has got to be heated with usual water heater during the winter period.
 -Cut your charges: Solar energy is free, due to the fact that after you pay for the solar hot water system prices will decline.
 -Reduced release of CO2: Heated water provided by natural ways, ie via green heating system, lessens CO2 emissions. So you should not wait for the next electrical bill with a part of worry, but set out to adapt to the new conditions of living and to create our apartment a lot more solar energy successful.
