4. Renewable Resource is a natural resource which
can replenish with the passage of time, either through
biological reproduction or other naturally recurring
processes. Renewable resources are a part of Earth's
natural environment and the largest components of its
ecosphere. A positive life cycle assessment is a key
indicator of a resource's sustainability.

9. Water can be considered a renewable material when carefully
controlled usage, treatment, and release are followed. If not, it would
become a non-renewable resource at that location. For example,
groundwater is usually removed from an aquifer at a rate much
greater than its very slow natural recharge, and so groundwater is
considered non-renewable. Removal of water from the pore spaces
may cause permanent compaction (subsidence) that cannot be
renewed. 97.5% of the water on the Earth is salt water, and 3% is
fresh water; slightly over two thirds of this is frozen in glaciers and
polar ice caps. The remaining unfrozen freshwater is found mainly as
groundwater, with only a small fraction (0,008%) present above
ground or in the air.

10. GEOTHERMAL

11. Geothermal energy comes from harnessing heat from the
Earth. A large utility company, for example, can directly use a
geothermal reservoir to drive generators and produce electricity for
their municipality. In contrast, residential heat pumps use the
shallow ground temperature of the Earth to heat and cool a home on
a smaller scale. The shallow ground temperature remains between 50
and 60 degrees Fahrenheit. Other applications put geothermal heat
to use in commercial buildings, roads, agriculture and industrial
factories.

12. WIND
NEXT

13. Wind is just moving air created as the sun heats the Earth's
surface. As long as the sun is shining, the wind remains an
infinite, renewable resource. Wind power is clean energy
because wind turbines do not produce any emissions. The classic
Dutch windmill harnessed the wind's energy hundreds of years
ago. Modern wind turbines with three blades dot the landscape
today, turning wind into electricity. Although wind only
generated little power in the United States in 2009, it is the
fastest-growing source of new electric power, according to U.S.
Energy Information Administration.

16. A biofuel is a type of fuel whose energy is
derived from biological carbon fixation. Biofuels
include fuels derived from biomass conversion, as
well as solid biomass, liquid fuels and various
biogases.

17. Bioethanol is an alcohol made
by fermentation, mostly from
carbohydrates produced in
sugar or starch crops such as
corn, sugarcane or switchgrass.

18. Biodiesel is made from
vegetable oils and animal fats.
Biodiesel is produced from oils or fats
using transesterification and is the
most common biofuel in Europe.
BIODIESEL
BACK

19. Biogas is methane produced by the
process of anaerobic digestion of organic
material by anaerobes., etc. is also a
renewable source of energy.

21. Hydropower is energy derived from the movement of water in
rivers and oceans, originally used for irrigation and the operation of
various mechanical devices. Since the early 20th century, the term is
used almost exclusively in conjunction with the modern development of
hydro-electric power. Conventional hydroelectric power involves
creating a dam, and using the resulting water force to turn a water
turbine and generator. Other electricity generating methods are run-
of-the-river hydroelectricity, which captures the kinetic energy in
rivers or streams, without the use of dams, and pumped-storage
hydroelectricity, which stores water pumped during periods of low
demand to be released for generation when demand is high.
BACK

22. Bioplastics are a form of plastics derived from
renewable biomass sources, such as vegetable fats and
oils, lignin, corn starch, pea starch or microbiota. The
most common form of bioplastic is thermoplastic
starch. Other forms include Cellulose bioplastics,
biopolyester, Polylactic acid, and bio-derived
polyethylene.

23. BIOASPHALT
Bioasphalt is an asphalt alternative made from non -
petroleum based renewable resources. Manufacturing
sources of bioasphalt include sugar, molasses and rice,
corn and potato starches, and vegetable oil based
waste. Asphalt made with vegetable oil based binders
was patented by Colas SA in France in 2004.
