chest freezers are more energy and money efficient,but if you have the money upright freezers are far more convenient. chest freezers provide more insulation therefore saving money.
Infrared Heaters are generally more cost efficient then regular space heaters. The reason is that they heat the object directly rather then heating the air, so it wastes less engergy. Ive seen estimates that say its as much as 80% more energy efficient.
distillation. Boiling the solution requires more energy than the energy content of the ethanol present.
No, its more energy efficient.
Nuclear energy is a very clean source of electricity. There are no pollutants put into the air, and it is very efficient.
a regular light bulb emits about 80% heat energy and only 20% light energy, whereas leds emit about 70 % light and 30% heat
They say chest freezers are superior, but its up for debate depending on who you talk to
Manual-defrost freezers are generally more energy efficient and quieter than self-defrosting models. But defrosting can take hours.
The best brands of upright freezers are Fisher & Paykel, SunBeam and Thermador. They use the least amount of electricity as certified by EnergyStar, with Fisher and Paykel using the least.
Energy Star freezers are more energy-efficient than non-certified models, which can lead to lower electricity bills and reduced environmental impact.
Chest freezers are better because they use less energy, have more usable space and are cheaper. They are easier to organize though. You can read more differences at http://housewares.about.com/od/refrigeratorsfreezers/a/chestvsupfreezr.htm
Whirlpool makes the most energy efficient freezers for the average homes, only costing approximately $29 per year to run.
ENERGY STAR has qualified models that use less energy than older refrigerators. This is their site: www.energystar.gov
Most of the new appliances sold these days are energy efficient They usually have a motif sticker that says "energy star" or "energy efficient". Look at the wattage that the appliance uses. It is usually compared to what the older model used as compared to what the new one consumes. Refrigerators and freezers are a couple that fall into this category.
No, not all brands of freezers are energy star rated now.
The Haier ESCM050EC is one of many Energy Star rated freezers.
According to consumer reports on different websites, the best upright freezer is the Frigidaire 16.7, but the competition is very tight amongst other brands like Kenmore and Whirlpool. These are trusted brands that have been around forever
