Solar Energy. The sun produces energy through nuclear fusion At the basic level, the nuclei of hydrogen atoms fuse together to create helium atoms. Helium
The sun produces energy through nuclear fusion At the basic
level, the nuclei of hydrogen atoms fuse together to create helium
atoms. Helium atoms have less mass, and the remaining matter has
left in the form of radiant energy

Types of Solar Energy Passive Solar Energy Solar Thermal Power
Plants Solar Photovoltaic Cells (PV)
Slide 4
Solar Thermal Power Plants Solar thermal power plants use the
sun's rays to heat a fluid to very high temperatures. The fluid is
then circulated through pipes so it can transfer its heat to water
to produce steam. The steam, in turn, is converted into mechanical
energy in a turbine and into electricity by a conventional
generator coupled to the turbine -

Slide 5
Solar Photovoltaic Photovoltaics is the direct conversion of
light into electricity at the atomic level. Some materials exhibit
a property known as the photoelectric effect that causes them to
absorb photons of light and release electrons. When these free
electrons are captured, an electric current results that can be
used as electricity.

Drawbacks The amount of sunlight that arrives at the Earth's
surface is not constant. It depends on location, time of day, time
of year, and weather conditions. Because the sun doesn't deliver
that much energy to any one place at any one time, a large surface
area is required to collect the energy at a useful rate.
Slide 10
Wind
Slide 11
What is wind power? Wind is a form of solar energy. The sun
heats land differently than the sea. This heat rises and moves over
the water. This cool air pushes on the existing air, moving it
towards the land. This interaction between warm and cool air
creates wind. Irregularities of the earths surface and rotation of
the earth are other ways wind is generated. Wind turbine uses the
mechanical energy created by the wind to convert it to electrical
energy.

Offshore wind farms in NJ
Slide 16
I wonder What happens during periods of intense wind? How do
the cables transfer energy from sea to land How to get state &
federal permits? Any models in Europe that are comparable to this
project? The wind farms should be able to transfer energy up to
56mph. The cables would be underground. This is directional
drilling. Fed Permits come from MMS State ones come from NJDEP This
is the largest proposed wind farm to date.

What are your thoughts? Do you believe investing land space for
solar energy is a useful investment? How much of a factor does
aesthetics will sway your opinion? If you were a resident in an
ocean front area, would it ruin your view if you had to see wind
turbines? What other factors do you think need to be considered
before investing in these technologies?
