To help get better gas mileage check tire pressure and air filters. Air is pulled through the engine, and if the filters are clogged, it takes more energy to pull the air through the engine.
In the earlier stages of the industrial revolution, fuel sources were local and widely distributed. Industrial activity tended to grow in areas where local sources of coal were available. As the transport associated with industrialisation spread and developed, fuels began to be transported from more and more distant places.
Now, with the most accessible sources of oil and gas depleted, fuels are transported around the world from small number of major producing areas. The result is that the major industrial nations have become dependent upon supplies from those producing nations, in particular oil from the Middle East, and are highly vulnerable to disruption of these supplies.
This vulnerability and dependence has been a major factor shaping world politics. A series of major economic and political crises has resulted from Sues crisis in 1956 to the 1970s, oil crisis to the Gulf war in early 1990s. Since the producing nations are generally weak militarily and the consuming nations are generally stronger, latter are under pressure to dominate the former economically, politically and if necessary, militarily to maintain access to oil (most important fuel today).
A related aspect of vulnerability in the present form of industrialisation is the centralized nature of fuel production and distribution. Electricity is generated in relatively few, very large power stations, and distributed through the country. Oil is imported in giant tankers, and converted to fuel in large refineries for further distribution. Concerns have been expressed that these large, vital installations offer potential target for terrorists or military opponents.
As has been seen in recent years in the Middle East (Gulf War), the result can be massive ecological damage as well as economic devastation. The normal response to such vulnerability is to put greater resources into security and to increased level of protection. High level of centralisation leads also to problems with employment.
Decentralized energy production and utilization which is the case of renewable energy sources can create much more new jobs than centralized fossil fuel installations. Nuclear weapon proliferation is one of the biggest threat to the world peace today with several countries already in or trying to be a member of “nuclear club”. In developed countries nuclear electricity industries grew out of nuclear weapons development.
The earliest nuclear reactors were built to produce material for nuclear bombs. There has always been a close connection between the two terms of the technology used, so that military spending on research and development for nuclear weapons technology has in effect been a major subsidy for civilian nuclear electricity industries. Nuclear fuel is not directly useful for nuclear weapons.
Much further processing is needed. However, for a country wishing to develop nuclear weapons without publicly revealing the fact, an obvious approach would seem to be combine weapons development with a nuclear electricity generation industry.
Thus, the ultimate purpose is to conserve energy. With energy a scarce resource people across the world need to look at lifestyle changes to protect it around the globe. From driving less, to turning off a light in a room that is deserted, there are simple steps that can be taken to aid the cause. Conservation methods take thought, commitment and changes in every day lives to make a difference.
In order to conserve energy, consumers need to be aware of their daily usage and find ways to cut that usage. Conservation of Energy includes using less gasoline, electricity, and non-renewable resources to produce that electricity, recycling and home improvements. Not all methods of energy conservation will impact negatively in the daily routines of people. With a little consideration and a dedication to reduce energy consumption, everyone can do their part.
Reducing the amount of non-renewable resources used each day would make a large impact in the energy conservation movement. Sources of non-renewable energy include coal and fossil fuels such as gasoline, oil and natural gas.
To reduce the use of fossil fuels, driving vehicles, which use these resources, less will help in a big way. Driving fewer miles will save money as well, and reduce pollution produced by gas-fired engines. To help get better gas mileage check tire pressure and air filters. Air is pulled through the engine, and if the filters are clogged, it takes more energy to pull the air through the engine. Tire pressure is an important factor as well; if the tires are inflated improperly it will take more energy for the engine to push the car along.
When traveling long distances, map out the route that will be taken. Mapping the route can save both time and mileage, thus saving gasoline and money. Using less gasoline benefits the environment as well. There will be less pollution, and less need for the fossil fuel required to drive a vehicle.
