(2) Alternatives for Solving
Problems

Our
reliance on fossil fuel is dramatically increasing. Here, we must make a major
transition to an alternative energy resources that are sustainably usable in
order to survive in the future. In a long run, we must progress our technology
on nuclear fusion and the solar power. In a short run, human race have no
option but to rely on wind power, tidal power, nuclear, and developing Bio
fuel.

(3)Renewable energy

 

– Solar
Energy

Solar
energy is the sun’s rays that the sun’s rays reach the earth. This energy can
be converted into other forms of energy, such as heat and electricity.

-Wind Energy

Wind turns
the blades of a turbine, which in turn spin a shaft that is connected to a
generator. This produces kinetic energy, which the generator uses to produce
electricity

-Water
Energy

Hydropower
is power, usually electricity, that is generated by the use of water. For
example, Niagara Falls is used to generate electricity using large turbines
under the water which are turned by the energy of the falling water.

-Geothermal

The term
geothermal simply relates to the internal heat of the earth. Through this
people are able to obtain the geothermal energy and transform it into
electricity. Geothermal electricity does not require fuel, just pumps and
therefore environment friendly.

-Biomass

Biomass is
an organic material made of animals and plants. Biomass contains stored energy
from the sun. Some examples of biomass fuel are timber, crops, fertilizers and
some waste.

-Tidal Energy

Tidal
energy refers to a form of power that converts the efficiency of tides into
useful forms of dynamism. It is generated by the surge of oceanic rise and fall
of tides. This type of energy is renewable and that is one of the biggest
advantage it has.

-Wave Energy

Wave energy
refers to the act of harnessing and using energy that is produced by surface
waves from the ocean. This type of energy can be used for water desalination,
the generation of electricity and pumping water into reservoirs.

 

(4) What is the tidal energy and
why we are use this energy.

Marine
Energy converts ocean tide, wave, currents, and different of temperature to
produce electricity or heat. As for example, the method of producing
electricity has tidal, wave, and temperature difference development. The reason
is why we are use this is that tidal tides are used for the difference between
the tides. If we can confidently predict this planet, it is the difference
between the tides. This form of renewable energy provides a distinct advantage
over other sources of energy such as wind and solar power.
Solar power, or the wind turbine, is very much affected by the
climate. Solar power is less efficient during the rainy season or at night when
the sun is not rising, and the wind turbines cannot keep working, although they
are installed in windy areas. That is
because it cannot be windy all day long. Furthermore, people choose the tidal
energy among a lot of renewable energy. Because tidal energy is the most
efficient renewables. The tidal energy produced is clean and free from
contamination. And there is no CO2 and other by-products. It does not produce
greenhouse gases or other waste. We think the best renewable energy is tidal
energy. However, there are many drawbacks to tidal energy. So we had a debate
on the subject. However big the possibilities of marine energy are, the reality
is that we cannot develop and utilize them all blindly. It is also true that
some are skeptical about the development of the oldest tidal power generation
because of its influence on the ocean ecosystem

 

– Tidal power generation

When the
sea water flows in, the water is released into the breakwater, and when the
tide begins to flow, it is allowed to lock up again. Water is released at one
time and turbines are generated to generate power, making it the first time a
plant has developed such method of generation by sea energy. Tidal power
generation by installing breakwater on the coast to utilize the difference in
tide flow

– Wave-force
generation.

Using the
waves of the ocean waves, the power generation is propelled by the inflow of
air from the turbine to the bottom of the turbine. Technology of generating
electricity using sea or deep sea wave energy. Wave Power
is a method of converting of waves through the energy conversion to mechanical
rotational motion or to convert them into electricity after converting to
mechanical or axial motion. Unlike
tidal power generation, which develops by using the difference in tide flows by
installing breakwater on the coast, it is a turbine that turns on the ocean
floor by using current rather than a dam or a breakwater in the sea. As there
is no need to construct a breakwater, it will cost less than tidal power
generation, be allowed to navigate ships freely, and be evaluated as an
environment that does not interfere with the movement of fish

– Tidal stream power generation

Ocean water
conversion system since it is not necessary to build a breakwater, it is
considered environmentally-friendly because it costs less than the tidal wave
and is free to travel around the surrounding ecosystem without disturbing the
surrounding ecosystem.

– Thermal
difference generation

The ocean
temperature difference power is the temperature difference between the surface
layer and the deep layer around 20 ?. It evaporates the low-viscosity
media such as ammonia and Freon into the surface water, and then circulates the
turbine with the deep water
