Essay On Use And Value Renewable Resources

As Professor Foster explained the core of the needed ecological revolution is in viewing the world ecologically, which involves recognizing that modern human societies are ecosystem-dependent and thus rejecting the assumption that societies are “exempt” from the forces of nature. The wrong conceptual thinking that our technology and economic system can find solutions to our problems, recalls the Midas Effect in which Gold (THE CAPITAL) becomes more important than Life (Human beings and Planet Earth), where “the logic of capital accumulation runs in direct opposition to environmental sustainability” (The Ecological Rift, Foster,

Renewable resources can be used as things that come naturally within Earth and will not run out; including but not limited to solar power, wind power and hydroelectric power. According to Document B, “BP’s (British Petroleum) intention to step up investments in solar energy.” , “WIth twice the fuel economy and half the CO2 (carbon dioxide) emissions of conventional cars.” (talking about the world’s first hybrid electric car), and finally “Denmark now generates (some) of its electricity from wind power and ... from the combustion of agricultural waste.”. Using any and all of these renewable resources can be the start to a new beginning of the end of fossil fuels.

Firstly it can use most biodegradable organic matter including human and animal waste, sewage, etc. This is great as there is no limit to the fuel and it is easy to find. Secondly, it reduces cost

The renewable energy that the Georges produced through the bio-gas is set up to offset the farm's electricity use and/or sell the power at wholesale rates to the local utility. In the article it stated that the change to bio-gas results in less odor-causing compounds in manure in a liquid storage system and the breaking down of manure in the digester changes the organic nitrogen into ammonium which is when spread on the fields it’ll become more readily available when consumed by the plants allowing for less nutrient runoff. Also reduces weeds appearing in the fields causing less weeds growing with crops. Another great thing about the digestion process it also reduces methane, a greenhouse gas, emissions (basically global warming) which would otherwise remain in the atmosphere for 9 to 15

As the planet’s population continues to grow, so will the energy needs. Even with fast advancement of technology, humans are only able to extract so much oil in a given period. Relying solely on fossil fuels and pushing off the inevitable does not make sense. If all of the United States oil supply and every other non-renewable energy source had suddenly disappeared from the face of North America, Americans would have no choice but to rely on renewable energy resources and that would not be a problem. As more solar panels, windmills, and hydroelectric turbines were built and placed in their respective environments, the United States would be back on its feet within no time. This would eventually lead to lower energy costs and a much greener and environmentally friendly nation overall. In the long run, investing and focusing on renewable energy resources provides the United States with a fail-safe solution which would also provide citizens with the energy they need to power their everyday

She supports these claims with the use of two principles, “Nothing is Lost Principle” and the “Principle of Waste Avoidance.”

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

Initial consensus was hog waste could be used as fertilizer for neighboring crops, but as learned above, this isn’t exactly a solution to a problem but rather another problem in the making. In the long-term, waste lagoons tapped as manure sources to spray on fields is not sustainable as fields are unable to absorb the volume of waste generated by hog production facilities. To cut air and water pollution generated by hog waste, approximately 29 swine operators across the country use waste digesters that are considered biogas recovery mechanisms.12 The infrastructure of this costly system consists of slat covered barn flooring that hogs walk across, and as they defecate, their waste is routed to a large sized manure digester. This digester allows bacteria to decompose the waste for a set period of time and produces methane in the process. The methane gas produced travels through piping to a generator where it can be burned to create electricity a farm site can in turn sell. Through additional refinement, biogas can also be made into transportation fuel, i.e. natural gas. Any remaining waste not decomposed by bacteria would be routed to a waste containment lagoon and covered to limit wafting of noxious odors and avoid overflow due to rains. At this time, this method is considered somewhat cost prohibitive and interested parties are trying to find economical alternatives that may be

In this day and age, we have new energy sources that could be used to power our homes and transportation. Wind and solar power are used all over the world, but are still used far less than fossil fuels. Most would say it’s not reliable or it doesn’t make any profit. While both statements are true, it doesn’t mean we can’t make a better future using renewable energy. In fact, the only reason we don’t use renewables for everything is that we don’t want to change. The hard truth is we need to change. Fossil fuels are great right now, but if we run out, humanity must have another source of energy.

Since, fossil fuels have been a part of our environment for some time now, they have been the main resource we’ve needed and used to keep our country running. The truth of the matter is, since we obtain fossil fuels from plants and animals that lived millions of years ago they will soon be gone. As indicated by Eric McLamb, founder, chief executive officer, and president of the ecology communications group, “The problem is fossil fuels are nonrenewable. They are limited in supply and will one day be depleted.” People realize that the crisis of running out of fossil fuels is upon us; however, these same people are timid about moving on to renewable energy. One main reason is because individuals do not believe renewable energy is cost efficient. For instance, solar energy is known to be fairly expensive, particularly more expensive than the conventional energy used now, which makes people uncertain about changing to renewable energy.

As the world population rises, we are using more and more energy and it is depleting faster than ever. Our fossil fuels (coal, oil and natural gas) will not last forever and at some point we will have to switch over completely to renewable energy sources. While most of the world still uses non-renewable energy sources, the future will rely on renewable energy and its applications. Right now, over 90% of the world still uses fossil fuels and developing countries even burn wood to generate energy. At the rate we are using our fossil fuels, they will not last us far into the 22nd century. Additionally, big consumers of fossil fuels like China, U.S., Russia, and India are creating large amounts of pollution and it is only increasing. For instance, India has major issues with pollution because of heavy traffic (which releases more fuel emissions into the air), the burning of biomass (wood and other organic matter), and runoff into lakes and rivers. Right now, our biggest goal should be to figure out how to implement more forms of renewable energy in our own society. We should start using renewable energy in America because: it is more environmentally friendly, opens up the job market, and improves the health of the public.

Renewable resources are also known as alternative energy sources. Alternative Energy is any source of energy that can be renewed (Issit). Renewable Energies include hydrogen fuel, biomass fuel, hydropower, solar power, geothermic energy, and nuclear power. Hydrogen fuel is an amalgamation of hydrogen and oxygen which is used to produce electricity (Issit). Biomass fuel is made from materials which have already been used, such as compost, and can be used to generate electricity (Issit). Hydropower can be created through moving water or wind to generate electricity (Issit). Using sunlight to produce electricity is called solar power (Issit). Geothermic energy is energy made by the heat under the earth’s mantle (Issit). Nuclear power is

Methane is one of the important green house gases and its production in India is 105 Tg/year, out of which about 60% is produced by enteric fermentation of ruminants. About 92% of it is produced only by cattle and buffalo and 8% is generated by all other herbivorous animals like sheep, goat, yak, mithun, horse, elephants etc. The mitigation techniques of methane include plant secondary metabolites (tannins, saponins, essential oils and alkaloids containing plants), inorganic terminal electron acceptors (nitrates and sulphates), chemical composition of feed (concentrate/roughage ratio) and chemical and microbial intervention. By using these techniques individually or in combination, might lead to 30-40% methane inhibition.

Anaerobic digester (AD) systems produce electricity and heat from the biogas produced from organic inputs. Farm-based AD systems represent a significant opportunity for farmers to capture new value from agricultural product and byproducts, and from some off-farm organic inputs. As farm-based green energy becomes a new on-farm product, more and more farmers will be looking at ways to finance and build AD systems.

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
