Fuel Efficiency
What is fuel efficiency ?
-The amount of work obtained for the amount of fuel consumed. In cars, an efficient fuel allows more miles per gallon of gas than an inefficient fuel cars.
Why is fuel efficiency important?
-You can save $200-$1,500 in fuel costs each year by choosing the most efficient vehicle that meets your needs. This can add up to thousands of dollars over a vehicle’s lifetime. Fuel-efficient models come in all shapes and sizes, so you don’t have to sacrifice utility or size
What are some ways we can be fuel efficient?
1)don’t drive if you don’t have to. If you have to drive minimize the time you sit in idle. Make sure your tires are inflated to save 3 billion in fuel
2)news is that about 42 percent of your household energy costs go toward just two things - heating and cooling. The good news is that means you have a lot of room to make a difference and even small changes can make dramatic improvements in household fuel efficiency.
3)Replacing older heating and cooling systems with new efficient models can cut your annual energy costs by 20 percent. So replacing the old with the new is a wonderful idea, but not very practical for most of us. Things you can do right now to make sure you’re maintaining the right temperature in your house efficiently include:
4)Tune up your heating system. By keeping your furnace clean, lubricated and properly adjusted, you can save up to 5 percent in heating costs.
5)Clean vents, close unused vents, and change filters in the vents. Again, just these simple things will save you up to 5 percent in costs.
6)Buy a programmable thermostat, which can regulate different temperatures at different times of the day. And if you have one, use it! These thermostats reduce energy use by 5-30 percent and save you $100-$150 in energy costs each year.
7)If one in 10 households serviced heating and cooling systems annually, cleaned or replaced filters regularly, used a programmable thermostat and replaced old equipment with ENERGY STAR models it would prevent the emissions of more than 17 billion pounds of greenhouse gases.
8)Add two degrees to the AC thermostat in summer, and two degrees in winter. If everyone did this, the cumulative impact is significant.
9)Make sure windows and doors are sealed. Again, this will dramatically improve your household fuel efficiency. Sealing air leaks and adding insulation can reduce your annual energy bill by 10 percent.
10)Of course, if you can stand it, by far the best approach is to avoid using air conditioners. Ceiling fans use 80 percent less energy than central air conditioners. By only using ceiling fans you can reduce your annual cooling costs by 10-65 percent. In warm weather run the fan blades in a counter-clockwise direction to feel 5 degrees cooler. During the winter set the fan blades to rotate clockwise at a low speed to force warm air from the ceiling down into the living space.
What countries leading in fuel efficiency?
-Most of UK and Europe is trying to help save the world.
Why are they leading in fuel efficiency?
1)6 Aircraft engine emissions are directly related to fuel burn. Each kilogram of fuel saved reduces carbon dioxide (CO2) emissions by 3.16 kg. So the key for airlines to minimise their environmental impact is to use fuel more efficiently. Airlines improved their fuel efficiency by 5% in 2004-2005 alone. Through gradually incorporating advanced technology into their fleets, airlines have made impressive fuel efficiency improvements.
2)However product development cycles are long around 15 20 years. Plus most airlines already use advanced technology and processes making additional fuel efficiency improvements more difficult and expensive
How can we make car’s more fuel efficient?
Snow Blower
-Keep your car tuned-up properly.
-Add fuel injector cleaner to your gas tank.
- Have your car’s oil changed every three months.
-Check the air pressure in all four tires.
-Have the engine belts checked regularly for wear or cracks.
-Have the air filter checked every oil change
-Avoid periods of unnecessary idling time.
-Driving your car past 55 or 60 miles per hour takes more fuel.
-Use the cruise control feature in your car so you are not speeding up and down.
-Avoid unnecessary acceleration along with sudden braking. This jerky starting and stopping of your car wastes fuel.
