Effects of global warming Global warming can bring many long-lasting and devastating consequences to Earth and all its occupants. It is a well-known fact that global warming is real and is caused by human activity‚ primarily the burning of fossil fuels that pump carbon dioxide (CO₂)‚ methane and other greenhouse gases into the atmosphere. One of the most noticeable effect of global warming is ice around the Earth is melting‚ especially at the Earth’s poles. These ice includes ice sheets covering

The Diesel Engine Diesel engines are very similar to the gasoline engine you may find in a car. They both are internal combustion engines‚ have a four stroke cycle‚ and convert chemical energy from fuel into mechanical energy. However‚ the manner in which the combustion stroke is attained sets these two engines apart‚ and although a seemingly meaningless change‚ a large change in efficiency results. (Diesel Engines vs. Gasoline Engines) The diesel engine was invented by Rudolf Diesel in 1892

in the Market of Fuel-Efficient Cars “In the past‚ nothing slowed down strong car sales faster than a spike in gasoline prices.” Gasoline and normal cars are strong complements because gasoline is necessary for cars to operate and forms the large bulk of the cost of owning a car. The quantity demanded for cars decrease more than proportionately to the increase in prices of gasoline. “These days‚ consumers simply switch to more fuel-efficient models. The choices for fuel efficiency are so

When you buy an offset‚ you fund projects that reduce greenhouse gas emissions Tidal & Wave Energy: Pros Wave Energy does not produce any GHG emissions or cause air pollution from the combustion of fossil fuels unlike coal‚ oil or gas. Wave Energy does not require any fuel like most other sources of energy. Wave Energy does not lead to pollution disasters like the BP Oil Spill and Coal Deaths which are directly related to Dirty Energy Production. Wave Energy Generators can be installed

They can run on a variety of fuels‚ including natural gas‚ propane‚ and fuel oil. • The other advantages over other types of DG technologies are a small number of moving parts‚ compact size‚ lightweight‚ good efficiencies in co-generation‚ low emissions and can utilize waste fuels. Maintenance costs for micro-turbine units are still based on forecasts with minimal real-life situations. Disadvantages: •The major issues involved in micro turbines are the low fuel to electricity efficiencies

of a self-adjusting engine. 1981 saw the first of these self-adjusting engines. They were called feedback fuel control systems. An oxygen sensor was installed in the exhaust system and would measure the fuel content of the exhaust stream. It then would send a signal to a microprocessor‚ which would analyze the reading and operate a fuel mixture or air mixture device to create the proper air/fuel ratio. As computer systems progressed‚ they were able to adjust ignition spark timing as well as operate

The world is undergoing a transition period between a phase of fossil fuel energy to a phase of clean and renewable energy. There is urgent need for the planet to develop a new range of renewable energy sources which are less carbon intensive and which will open up a new age for fuels. In such a scenario‚ the 21st century will be a transitional period for energy generation and consumption. It is probable that the world is moving towards a greater diversity in primary sources‚ in which each country
