现在电费好贵啊，看到说ACN现在是5.69/KWH, 价格算是便宜的，但不知道这公司靠谱吗？有人用过不？
10 Energy Saving Tips
Tip 1
If it's not in use, turn it off. If possible, unplug rarely used electronics as these 'vampire devices' tend to draw off a trickle of electricity constantly.
Tip 2
Dress for the weather and relax your thermostat 1-2 degrees. The larger the difference between indoor and outdoor temperatures, the more it will cost to heat your home per degree. It costs more to get your house from 21 to 22 than it does from 20 to 21. When you drop your thermostat by just 1-2 degrees, you are dropping it by the most expensive part of your furnace's work.
Tip 3
Fans cost less to run than air conditioning. On summer nights, use fans to cool the house. Ceiling fans are especially effective.
On warm summer days, your house may be kept reasonably cool by trapping cold air in the house at night and then keeping windows closed during the day.
Tip 4
Make sure your hot water heater is not set too high for your family's needs. Turn your hot water down until you find you are running out of hot water more often than you'd like, then set it a little bit higher than that.
Take five minute showers instead of baths. Only wash full loads of clothes and dishes. Use cold water for laundry with specially formulated cold water detergents.
Install low-flow shower heads and sink aerators to reduce hot water use.
Tip 5
Close the heat vents and doors in seldom used rooms.
Tip 6
When buying new appliances, look for the ENERGY STAR™ label and rating.
Consider investing in a power-usage monitor (typically around $25) to check the efficiency of your existing appliances, and see where you use the most power. An old inefficient refrigerator can use as much as $30 per month in electricity, compared to just $4-5 per month for a high-efficiency fridge.
Consider cooking with a microwave, electric skillet or toaster oven. These small appliances are more efficient than stovetop pots and larger oven.
When using the stove, keep lids on pots to hold in the heat.
Tip 7
Old-style incandescent light bulbs convert 95% of energy used into heat, not light. Use fluorescent light bulbs in the most used locations. They last up to 10 times longer and use one-third as much energy.
Compact fluorescents have come a long way from the days of their flickery ancestors. CFL bulbs are even available in a variety of colour temperatures (daylight, incandescent, etc.).
Another option on the horizon are LED bulbs which are even more efficient, and don't contain mercury as compact-fluorescents do. They are unfortunately still quite expensive but have incredibly long life-spans.
Tip 8
Add more insulation in the attic until there's 6-10 inches of depth (R-38 to R-49).
Inspect and repair (if necessary) the caulking and weather stripping around windows and doors once every other year.
Tip 9
Upgrade your windows to better insulating models. This can improve efficiency by 25-50%. Windows with fiberglass or vinyl separators between panes are especially good as they don't conduct heat as quickly as traditional aluminum separators do.
Tip 10
Plant trees! Trees can shade your house in the summer and, when the leaves drop in the fall, allow sunlight to warm your house in the winter.
