Homework Problems –Lecture 1
What would you recommend to overcome the challenges facing the wide use of wind
In order to overcome the challenges facing the wide use of wind power I would
recommend multiple actions such as increasing government subsidies on large scale
wind farms, increasing research and development of wind farms, increasing public
education and knowledge of wind power, and invest heavily in offshore wind farm
installation/maintenance techniques.
The barrier to entry and initial upfront costs in installing and building wind farms
when compared to alternative sources of energy, both renewable and non-renewable, is
a huge detriment to consider starting to build wind farms. By increasing research and
development of these wind farms and wind turbines you could make it even more
economically viable as an option to be installed and used over other forms of energy.
Furthermore, by educating the public and helping people to understand the
value of investing in wind farm technology to provide cheap energy that does not
produce any greenhouse gases would help push the federal and state governments to
invest in wind farms. The same situation could follow occur in the private sector as well
with corporations fulfilling the needs and wants of its customers. It would also be great
to get the public to understand that wind farms do not seriously cause cancer en mass,
kill an obscene amount of birds, or cause global warming due to the warm power cables
running underground (https://www.pressherald.com/2018/10/04/wind-power-canraise-global-temperatures-harvard-study-finds/).
Finally, currently in the U.S. when compared to Europe. The amount of resources
and know-how to install and maintain offshore wind farms cost effectively is lacking.
Currently, there is a big push in the offshore industry to create offshore wind farms in
the Northeast, but the specialized knowledge and resources to conduct this work is only
found vastly in Europe.
What financial incentives are there in your state for the use of wind power?
In New Jersey the current financial incentives for the use of wind power are
offered through the New Jersey Board of Public Utilities (NJBPU) through their
Renewable Energy Incentive Program along with New Jersey's Clean Energy Program.
Unfortunately, due to three failed wind projects there is a temporary hold on these
programs related to wind power.

When it comes to offshore wind farm wind farm development, New Jersey does
offer financial incentives though the Offshore Wind Economic Development Act
(OWEDA). The NJBPU awards Offshore Wind Renewable Energy Certificates (ORECs) to
companies developing offshore wind. These are subsidies from the state to help offset
the costs involved with creating the farms. This also helps the company building the
projects to qualify for federal tax incentives at approximately 12% of the total project.

Does the Federal Gov. provide any tax breaks to encourage usage of wind power?
Yes, the Federal Government provides tax breaks to encourage the use of wind
power in the form of Production Tax Credit (PTC), but unfortunately that is being phased
out this year. At the time of its inception in 1992, it helped start the wind power
industry in the United States and create a decently healthy industry. The hope is the
long lasting benefits of PTC will keep the industry going.

An office employs a space heater with a rating of 30 kW, a refrigerator (for snacks)
that is rated for 5 kW and a light fixture with bulbs that dissipate a total of 2100 W, all
operating at a constant rate for 8 hours.
(a) What is the total power consumed at any given moment?
30 kW + 5 kW + 2.1 kW = 37.1 kW
(b) How much energy is consumed in 8 hrs.?
37.1 kW * 8 hours = 296.8 kWh
(c) Assume the local power company charges 11 cents per kWh, how much
does it cost to operate the office for 8 hours?
296.8 kWh * $0.11/kWh = $32.65
What are the advantages/disadvantages of wind power?
Zero greenhouse gas emissions
Cheapest source of renewable energies
Provides income to farmers, ranchers,
and landowners in land lease payments
The variability of size of wind turbine
o Allows for remote off the grid
Promotes global security of the energy
market in the global economy while
helping the global environment
Can increase manufacturing and create
thousands of jobs
Variability of the resource
Requirement for large investment in
o Large initial cost (especially for
smaller scale projects)
Impact on the environment
o Harm to wildlife (birds, bats,
Significant amount of land needed
o For offshore projects,
commercial fishing grounds are
Reliance on government subsidies due
to initial high cost
