this topic ain't about music directly
but I supposed that a thrash fan cares about the earth he lives on..
so I wanna talk about some problems that influence the earth and our lives.
this is about passive solar energy..
Many different techniques can be used to convert sunlight into useful forms of energy. Active and passive solar energy technologies are generally used for space conditioning (heating and cooling), while solar electric technologies such as photovoltaic cells convert sunlight into electricity. Although the distinction between active and passive solar is blurry, the use of integral building components to capture the sun's energy is considered passive solar. Active solar technologies are generally add-on features which utilize mechanical means to distribute captured solar energy. An example of active solar energy is a solar hot water heater, while passive solar features may be as simple as south facing windows.
Passive solar building features can be used to heat and cool buildings, as well as provide light. The best time to incorporate passive solar technologies in a building is during the initial design. Passive solar features can often be included in new buildings without significantly adding to construction costs, while at the same time providing energy savings of up to 40%. Designing the buildings we live and work in, to capture the ambient energy of the sun through passive solar features, is one of the least expensive and most environmentally friendly methods of providing for our energy needs.
Each year, an enormous amount of solar energy reaches the earth's atmosphere. Much of this is reflected back into space by clouds before it reaches the planet's surface. Ninety-nine percent of the sunlight which does reach the ground is converted into heat (the other 1% is captured by plants through photosynthesis) and radiated back into space. If only a small fraction of this energy could be captured, the world's energy demands could be met. Even in cold climates like Canada, the amount of useful solar energy reaching the ground in the winter is greater than the daily heating requirements of a well insulated house.
The capture of solar energy by passive solartechnologies has almost no negative impact on the environment. Passive solar energy gives off no air or water emissions and therefore does not contribute to any of the environmental problems such as acid rain and global warming, which are associated with other source of energy. The sun is also a virtually inexhaustible source of energy which is "renewable" and will never become depleted like fossil fuels.
There is nothing new about using the sun's energy to heat our living spaces; humankind has used passive solar techniques for thousands of years. In the last century, cheap and abundant fossil fuels have led to the abandonment of passive solar building design. Rediscovering passive solar energy and incorporating technological advances can go a long way towards creating a more sustainable energy future.
REMEMBER THIS FACT; some men(!) don't support the solar energy and wanna use petroleum in spite of it's cause of too many environmental problems!
I wonder why!!!!!
look at the middle east and ask why..
so,
SUPPORT THE SOLAR ENERGY!
for more healthy and better world
