The global energy crisis is approaching. What can we do? Here are some steps you can take.
Cooling puts the greatest stress on your summer energy bill and the power grid(电网). Just as a tune-up for your car can improve your gas mileage, a yearly tune-up your heating and cooling system can improve efficiency and comfort. Clean or replace filters monthly or as needed.
For central air conditioning systems and room sir conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Ratio(SEER).
Use energy-efficient ceiling fans either alone or with air conditioning Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat(恒温器)and cut costs. Ceiling fans cool people, not rooms, so before you leave, turn off the ceiling fan.
Let a programmable ibermostat “remember for you”to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.
Cut your air conditioning load, and reduce pollution by planting leafy trees around your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid beat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs(荧光灯), which provide bright, warm light while using at least two-thirds less energy, producing 70 percent Jess beat and lasting up to 10 times longer than incandescent bulbs(白炽灯).
Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 miles per gallon to one that gets 30 mpg will save you more than $65 per year.
Carpool. The average U.S. commutes(乘车上班族)could save about $260 a year by sharing cars twice a Week with two other people in a car that gets 20.1 mpg—assuming the three passengers share the cost of gas.
1.Acoording to the passage, the thermostat is used to ________.

To meet the global climate crisis that is approaching, big lifestyle changes are required of those of us. The good news is that our way of life can remain meaningful and worthy as our consumption becomes sustainable(可持续发展的).
1. Eat less meat and move toward a plant-based diet. This is one of the most effective things we can do because the food we now produce and consume is destroying the very ecosystems that we depend upon for survival. Here are some of the grim facts.
The U. S. uses about one-half of its land for agriculture. 2.For example, the U. S. uses over 90 million acres of good agricultural land to produce corn, which is mostly fed to livestock(家畜).
With 7.6 billion people on earth, the demand for food is enormous and constantly on the rise. It’s easy to feel we can’t make a difference. 3.We should not ignore the power of the choices we make.
Even one person can make a big difference by eating less meat and moving toward a plant-based diet and make contributions to the health of the planet as well as your own. Recognize how the food we eat is connected to other living beings. It often helps us make much wiser buying choices. 4.This way, we will help people around the world enjoy more eco-friendly and nutritious foods.
5.When you change your diet to be more sustainable, you become visible proof that changing our food habits is doable, healthy, and enjoyable.
A. Little things matter in your relationship with the earth.
B. By buying mindfully, we support local, affordable agriculture.
C. But we can change our diet to heal the earth as we heal ourselves.
D. Unfortunately, the majority is used to raise livestock or for crops consumed by them.
E. Your choices create positive impacts on the food system and inspire the people around you.
F. There’s one step you can take right away to reduce harm to Mother Earth.
