One form of Biofuel involves using the waste from landfills by recycling the
gases that a landfill releases. Several landfills are now doing this and
supplying their own electricity and supplying others with electricity. We
could also use garbage to create fuel for our vehicles.
Biofuel can be used for the same applications as fossil fuel that is extracted
from the earth, but is cheaper and the burning of these fuels causes less
pollution to the environment than using fossil fuels as well as being more
environmentally friendly in the production. You can heat your home, create
electricity and run your vehicles on Biofuel.
An estimate of 40 billion gallons of cellulosic ethanol could be produced from
plant waste destined for the landfill, providing as much as one third of all
U.S. transportation fuel needs. If other forms of waste, such as the stalks
of corn plants (corn stover) or the remnants of timber harvest are included,
"we would have enough feedstock in the U.S. to offset 70 percent of the oil
import." A percentage that deserves far more study than is currently being
given to these processes.
We can also turn manure from ranching into biofuel.
Another type of biofuel, is called "Agrofuel", and it is fuel which is produced
from plant crops, such as sugar cane, beet, sweet sorghum, corn and
hemp(not marijuana) to produce ethanol. Another is to grow plants that
produce oil, such as vegetable oil, oil palm, soybean, hemp(not marijuana),
algae and others. When heated these oils burn in a diesel engine.
I look at these with the knowledge that at this time, many of these products
are being grown, such as oil palm, in a way that is harmful to the
environment, and this practice would need to be addressed to allow the
benefits that is possible with these products.
We could make plant type choices that would be far more reliable, cheaper
and environmentally friendly than some of the choices being used now.
First generation biofuels contain sugar, starch, vegetable oil or animal fats.
Second generation biofuels include the use of straw, timber, manure, rice
husks, sewage and food waste. Another positive of using these for fuel, is
that this also assist us with our waste management. Second generation
biofuels are non food crops, such as waste items.
Third generation Biofuels, at this time is made from algae.
Basically, we have the technology and the ability to create energy/fuel for
continuing to live in the lifestyles that we as modern day humans like,
instead of staying in the dark ages by continuing to use fossil fuels.
One quick statement here about hemp, it is NOT marijuana. I get so
irritated when I see people continuing to view and speak of hemp and
marijuana as the same plant when they are not. They are the same in the
exact manner that mushrooms and shrooms are the same, they are related,
but hemp like mushrooms do not get you high, marijuana like shrooms
does. They are the same as in you and your "cousins" are the same, but
obviously different. It seems that people like to ignore information, and live
in denial, believing that mushrooms/hemp and shrooms/marijuana are the
same, when the truth is brought up, people put their hands over their ears
and yell "la la la I can't hear you". The government has done a great job
with the disinformation in regards to Hemp. If you don't believe me, do
your research, the truth is out there.
Geothermal power is cost effective, reliable, and environmentally friendly,
but has previously been geographically limited to areas near tectonic plate
Recent technological advances have dramatically expanded the range and
size of viable resources, especially for direct applications such as home
heating. Geothermal wells tend to release greenhouse gases trapped deep
within the earth, but these emissions are much lower than those of
conventional fossil fuels.
Geothermal plants can be equipped with emissions-controlling systems that
reduces the exhaust of acids and volatiles further decreasing the amount of
pollution they cause.
Also, elements such as mercury, arsenic and antimony can be injected back
into the earth instead of disposed into rivers etc. I would wonder if in the
future we could come up with an even better way to protect th
environment from these substances.
We are still studying and learning about geothermal uses and so many
unknowns still abound in regards to geothermal energy. I advocate that it
is a possibility that deserves more study.
I am going on the assumption here that most people know about the
possibilities of solar power, and with the advances in solar technology that is
taking place, I see where in the future, it will become more available to the
Solar energy can be used for more than just creating electricity. Such as
heating and cooling through architecture, creating potable water via
distillation and disinfection, lighting through the use of skylights/domes etc.,
hot water, and the use of thermal energy for cooking.
Reading about solar power I learned more about the differences between
passive solar and active solar.
Active solar techniques use photovoltaic panels, pumps, and fans to convert
sunlight into useful outputs. Passive solar techniques include selecting
materials with favorable thermal properties, designing spaces that naturally
circulate air, and referencing the position of a building to the Sun.
