The major difference I found between Brazil and
the US’s energy policies was that the US is significantly further ahead in
their development of renewable energy sources. For example, all major
appliances and new cars are required to meet certain energy efficiency
standards. In Brazil, many policies were discussed that hoped to implement
these sort of standards but at the moment there was none in place. This was
mostly due to energy efficient appliances being expensive and not reasonable
for poorer communities. As a whole though, both countries see the need for clean,
sustainable energy and wish to reduce our carbon emissions in order to
stabilize the climate. Each discussed putting resources towards this
development, both through the use of government subsidized funding. Nuclear
power re-examination was another major discussion point and each country wants
to explore it further.
In the USA, these proposed policies have
effects environmentally, socially, and economically. Environmentally,
these policies substantially have reduced our carbon pollution, HFC emissions,
and methane emissions which resulted in a reduction of climate change. Through
these policies our natural resource consumptions has slowed down, leading to
the conservation of our land and water sources as well as agricultural
stability. These policies have affected our society by the establishment of
more structurally sound communities and improved disaster relief strategies.
For example, the Federal Emergency Management Agency and the Department of
Energy during hurricane Sandy shed light on the importance of policies to
address the restoration of communities’ fuel and electrical supplies post
disaster. Economy, reducing carbon emissions by transitioning to renewable
sources and by improving the efficiency of motor vehicles has reduced the
consumer’s fuel and energy bills. Because consumers are seeing a positive
effect on their personal finances, this leads to increased community support of
renewable development.
As in the US, introducing
policies to curb carbon emission and develop renewable technologies has effects
on the environment, economy, and society. Economically, these policies will
hopefully through efficiency improvements leading to a decrease in energy
demand growth lead to a reduction in investment requirements. Also, Brazil’s
trade balance will be improved through these policies through natural gas and
petroleum import reduction. Also, domestically, product of new technologies
will boost the economy and reduce trade dependence on other nations.
Environmentally, these policies would increase energy efficiency and expand
renewable use, such as with ethanol, wind, solar, and sugarcane products.
Another aspect would be a reduction of CO2 and NO emissions. Socially, these
policies would provide electricity to remote areas that otherwise would not be
able to be reached by the grid.
The US is far too reliant
on fossil fuels. As with any situation not just energy, you cannot sustain
yourself using a resource that is finite or that the usage exceeds the
regeneration. The usage of fossil fuels is only a temporary source of energy
and unless we develop alternative means we will run out in the near future.
Options for alternative energy we have are solar, wind, geothermal, hydroelectric,
nuclear, and natural gas. Solar energy through the use of photovoltaic cells
has the capability to provide enough energy for a common household but contains
economical limitations and has issues with indeterminacy Optimizations with
efficiency and material costs are needed to scale down on expenses as well as an
energy storage system for cloudy days or at night. Wind power takes up a
substantial amount of space, leading to environmental controversy and is only a
reasonable option in windy areas. Hydroelectricity leads to the issue of
requiring damming of rivers which also has adverse environmental effects.
Nuclear power has significant potential but runs into issues with risk of
overheating and where to dispose of radioactive waste. Natural gas although a
fossil fuel could be an effective transition fuel from oil to renewable and buy
us more time to develop these technologies.
I agree that we are dependent on fossil fuel but our way of living will only change when the effects of climate change have a more physical presence. When the time comes I hope there has been enough research into renewable energy to counter act the effects of less fossil fuels and climate change.
ReplyDeleteThe US and Brazil are exploring different alternative energies, US with natural gas and Brazil with hydro plants and ethanol. Given that natural gas is not sustainable, do you think that Brazil has done a better job at selecting a more efficient and sustainable alternative energy?
