Calculate going green. Here, basic math required to live sustainably. Formulas we can use to calculate our consumption rates. Analysis of our habits for lifestyle decision making purposes. To give us options for saving electricity from unplugging stuff to purchase decisions in the future. We can make sacrifices elsewhere in order to use a lot in other ways.
- Energy efficiency is to improve output while decreasing input.
- Fossil fuels give us most of what we need. But, it’s dirty.
Quantify sustainability for a more ecofriendly lifestyle. Millennials who use social media. Professionals doing work at home. Students distance learning. At a desk with pencil and paper. On a device. At the time we are budgeting we plan. As ecofriendly opportunities present themselves.
20 to 40-year-old people who pay electricity bills calculate home appliance energy efficiency ratings. Ratings, home Kilowatt Hour, Watts appliance Kilowatt hour formula calculation, voltage amps Kilowatt formula.
Understand, good to know and calculate. But, sellers and manufacturers have labels. There is a difference between A+, A++, and A+++ appliance energy ratings. We need electricity bills with consumption rates. Appliance voltage amps from devices. A calculator on our phone or laptop.
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.
Less resources in. More heat and light out. But, it is more complicated than that. In any event, various sources have different benefits and drawbacks.
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. We get an idea of our appliance usage so we can live sustainably.
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
First, find watts on label. Check bottom and back.
Next, Multiply watts by hours of use each day.
Then, Divide by 1000.
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.
First, Amps x Volts = Watts
Second, Watts x Hours Per Day = Watts Per Day
Last, Multiply 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.
