Renewable Energy sources
Fact: Renewable Energy sources can reduce Air pollution|
Fact: Renewable Energy sources can reduce water pollution
Fact: Renewable Energy sources can reduce soil pollution
Fact: Renewable Energy sources can reduce Health risk for humans
Fact: Renewable Energy sources can extend natural resources for our children
Sunlight is Earth's primary source of energy.|
The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight.
The solar constant is ~1,370 watts per square meter or ~1273 watts per 10 square feet.
All Renewable energy is directly
connected with our sun, can be called
Solar energyEnergy generated from what we call
E) Geothermal heat
What is the good thing about RENEWABLE energy sources?
They are naturally replenished by the sun:
Solar hot water/heating
Solar power photovoltaic
All renewable energy does not produce
air and water pollution
All renewable energy can be harvested
without burning fossil fuels.
Another good thing:
With about 119,000 jobs, the American
solar industry now employs much more
workers than the U.S. steel production sector
Renewable Energy BasicsMost countries currently rely heavily on coal, oil, and natural gas for their energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources; such as wind and solar energy; are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun's heat also drives the winds, whose energy is captured with wind power Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydropower.
BiomassAlong with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy
HydrogenHydrogen also can be found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
GeothermalNot all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides comes from the gravitational pull of the moon and the sun upon the Earth.
The ocean can produce thermal energy from the sun's heat and mechanical energy from the tides and waves. BSB conducts research in ocean thermal energy or ocean mechanical energy, gives advice.
HydropowerFlowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. BSB studies hydro-power technologies, give you Information.

The power of the sun can be used in many ways:
Heat = hot water
heat + power
Desalination of seawater
Solar design in architecture
Solar heating systems
Solar hot water panels
Solar thermal electric
with steam engine
with Stirling engine
Solar updraft tower
Solar powered car

Why to use renewable energy
Renewable energy producers use the power of our sun to transform sun energy to electricity with photovoltaic.
Butterflies lover renewable energy because
air pollution caused by burning fossil fuels ! KILLS them!
