57) The advantages of solar or wind energy are (as opposed to
fossil fuels):
A)they are non polluting B)the source of the
energy is free
C)they are found in nearly every country to some
degree D)localized production is possible
E)all of the above
58) The Endangered Species Act of 1973 authorized the United
States Federal Government to protect organisms listed as endangered
(in danger of extinction) as well as protecting the habitats of
those listed organisms.
A)True B)False
59)The idea that one's lifestyle...
Renewable sources of energy include photovoltaic,
solar thermal electric, wind, geothermal, and hydroelectric. of
these five types of energy, which one shows the greatest promise
for economic viability over the next 10 years. why do you say this,
and what obstacles, if any must be overcome to make this a
reality?
Waterloo North Hydro has two options for upgrading a geothermal
power station to meet new government standards. Assume all interest
is 4.19% compounded annually. Option 1 Waterloo North Hydro will
make the upgrades themselves. This is expected to cost $46,700 per
year from year 1 until the end in 21 years. At the end of the
operation (in 21 years) Waterloo North Hydro expects to sell all
equipment needed for the upgrade for $96,000. Option 2 Pay
experienced contractors. This...
Consider the markets for fossil fuels (oil,
coal, natural gas) and alternative energy sources
(solar, wind, geothermal power etc). Due to the current climate
change, let's say we desire to have people use less of the
fossil fuels (which produce greenhouse gasses that cause
global warming) and more of the alternative energy
sources.
Using the concepts of Supply and Demand, discuss how the
government can use policies to shift these curves, and what the
results will be on the quantities...
Passive and active solar energy systems are becoming viable
options to home builders as installation and operating costs
decrease. Laminated solar modules utilize high-quality,
single-crystal, silicon solar cells, connected electrically in
series, to deliver a specified power output. Research was conducted
to investigate the relationship between the solar cell temperature
(°C) rise above ambient and the amount of insulation (megawatts per
square centimeter). Data collected for six solar cells sampled
under identical experimental conditions are recorded in the table
attached....
Oil is an important source of energy. Extracting and
burning oil also causes ecological damage. Let Q be the quantity of
oil.
The demand for oil is given by: P = 80 - Q.
The aggregate marginal cost of producing oil is: MCpriv
= Q.
The monetized marginal environmental damage caused by
oil is: MCext = 40.
[5 points] Explain intuitively (but briefly!) how this
will cause the quantity of oil (Qm) transacted in the free market
to differ from...
Describe
active and passive transport. Which relies on diffusion and which
requires ATP? What are the different types of passive transport?
What are primary and secondary active transport?
In as much as Zimbabwe has quite a number of sources related to
geothermal energy production, give reasons why the technology has
not been installed in the country. In your answer state the areas
with sources. [20 MARKS]
