During the last three decades, the problem of global warming has been studied and analyzed from different perspectives. The main problems discussed by politicians and economists, ecologists and businessmen concerned the impact of human activities on global warming and climate change, and possible solutions to reduce the negative and harmful impact of pollution on ecosystems. Alternative energy resources are the only possible way to prevent global warming and preserve the natural environment from degradation and extinction of species. World growth cannot continue without energy constraints at rates near historic highs. In the first few decades some increase results in dependence on oil and gas, but this increase need be no more than is readily accommodated by world excess capacity. The main advantage is low cost and environmentally friendly design of collectors. Thesis Wind energy is one of the most cost effective solutions to traditional resources like coal, oil or nuclear power.
I feel that every citizen of the country could reduce energy consumption and use alternative energy resource. The threat of future shortages of liquid and gaseous fossil fuels can be relieved to some extent by converting coal to oil and gas. The liquefaction and gasification processes for coal may soon be as economical as obtaining liquid and gaseous fuels from conventional sources, and both processes seem likely to be used commercially within the 1970s. Reliance on coal for all fossil fuel needs would of course shorten the life expectancy of our coal reserves considerably. One possible alternative is the oil shelf, which constitute a potential energy resource much larger even than coal. Hydroelectric energy and the energy of the wind and tides will always be available. The rate at which these energy sources can be exploited, however, is limited by the global flow of energy in the form of falling water, wind, and tides at any given time. Power is the rate at which energy flows or is used (Beggs 76).
The second thing I would like to change is to reduce the number of green house gases damped into the air. In my house, o would introduce cost effective and environmentally friendly technologies such new oven working without gas. There are, however, serious problems in utilizing it to the utmost. Much of the potential lies in international conventions, where the power could not be used unless those countries were industrialized; global ecological factors and the inability of the international conventions, to mobilize capital and high-grade resources will impede industrialization in most of them (Beggs 23).
In order to protect the environment, I would buy a green car. It would help me to save money and protect my community from Co2. Looking forward, green car production presents new opportunities for policy makers and entrepreneurs, including farmers, as well as the new opportunities associated with global flows of goods, information, people and capital. The increasing integration of domestic and international markets limits the power of domestic policy to influence rural incomes independently of world market conditions. It also exposes countries to risks from external shocks and instability. In the current environment, governments must take account of how domestic agriculture is linked to global products and financial markets.
In sum, every individual must recognize that macroeconomic policies often have more impact on rural incomes than do agricultural policies; adopting sound policies that encourage savings and investment and widely-shared growth is ever more critical. Global warming is leading to a rising importance of consumer preferences in determining what is produced.
