Energy Efficiency Rating At Home

Energy Efficiency

Energy efficiency at home is a good place to start going green. After all, we live there. Plus, first two words are good house or apartment search terms. However, it’s deeper than that.

  • Power saving programs
  • Clean Tech
  • Green Tech

So, Ecofriendly power includes using less if we can. Then, we must have other options. As a result, buzz words are created for the new technology. Then, we must choose. To start, we have to know what we are dealing with.

Next, we need to compare. It follows, measures. After, we see what techniques are best. Then, we improve. So, it’s ongoing.

Energy Efficient Definition

Hence, getting power out of resources is necessary for our way of life. Thus, using less to do more is a solution to the problem of waste. Therefore, a principle. Given, we believe in getting better. Then, improving is natural, organic.

Thus, the definition is to improve output while decreasing input. Less resources in. More heat and light out. But, it is more complicated than that. For example, EnergyStar. In any event, various sources have different benefits and drawbacks.

For example, fossil fuels give us most of what we need. But, it’s dirty. Mostly, coal, oil, and gas. At the very least, particles are harmful to breathe. At most, a source of climate change.

Releasing less carbon to meet our needs is an overall goal of the equation. First, need less is a way. Next, get more out of it. Also, use another source. To understand, we must rate use.

Compare Electricity Use

At first thought, ratings must be science. Kind of, to a degree. First, oil, gas, and coal go into our grid. Next, electricity comes out. Thus, savings on both ends are rated scientifically.

But, ratings come from consumers, manufacturers, and government. Consumers have the grid. Manufacturers market products. Government regulates.

Power is a public utility. Hence, ratios are used to compare consumption. That way, we know how much we are using. There is a formula. However, that is for us coming from the grid.

For example, we use oil for gas in cars. Plus, heat in homes. Not really, on grid. First, oil is refined. Then, given an octane rating. And so, combustion inside engine gets us going. Higher ratings get better mileage. Less resources more output.

Energy Efficiency Formula

Then, less is more. As a result, we measure. And so, rating is done by kilowatt hours. Given, a formula with variable inputs.

After, public utilities give us periodic reports on our use. In addition, appliances display usage information. Therefore, two basic uses we need to know. Consequently, a few different formulas. Plus, some calculations.

Then, appliances can be measured. And so, we can reduce input. A couple of ways to figure that out. After that, we have a feel for balancing use based on our own lifestyle.

Home Kilowatt Hour Formula:

kWh = Kilowatt hours

1 kWh = 1000 watts

kWh x Price Per kWh = Total Bill

Watts Appliance Kilowatt Hour Formula Calculation:

Watts x Hours Per Day = Watt Hours Per Day

Watt Hours Per Day / 1000 Kilowatts

  1. First, find watts on label. Check bottom and back.
  2. Next, Multiply watts by hours of use each day.
  3. Then, Divide by 1000.
  4. Finally, use daily usage to estimate over time. And so, multiply by a number of days. For example, 30 is a month.

Voltage Amps Kilowatt Hour Formula

Home items don’t always display watts used. In this case, voltage and amps calculate them. Voltage is tricky. First, 120 watts voltage is standard in USA. Next, some stuff requires more.

  1. First, Amps x Volts = Watts
  2. Second, Watts x Hours Per Day = Watts Per Day
  3. Last, Multipy Watts Per Day times a period of days.

Now, back to the first equation for some management decision science. Thus, we can compare components of utilities for cost and efficiency. Just, multiply cost per kWh to compare.

For starters, do it now. Add up all your energy. Finally, save.
