George began dedicating his life to researching new ways to make the world a greener place. His expertise ranges from organic gardening, to renewable energy, to eating plant-based diets. He is currently writing and editing for a number of publications, most of which focus on the environment. ...
we can move on to preparing for our conversation with a battery specialist. Much like the term “watt-density” is used by heater designers, the term used in the battery world is “amp-hours.” An amp-hour is a unit of measurement used to express a battery’s capacity over time. This...
The monitor’s display will show you how many watts of electricity the appliance is currently consuming. More sophisticated monitors can track usage over time in watt-hours and kilowatt-hours (kWh). Some even allow you to input your electricity cost per kWh to calculate how much money the ...
Count the running watts of your appliances. Add up the running watts of the appliances you plan to use plus the starting wattage of the appliance with the highest starting wattage. Calculate the sum. That final number is the total starting watts you need from your generator. As discussed abov...
After natural gas passes through a meter outside of a house, the gas is piped to where it is needed inside -- to a furnace or boiler, water heater, or gas fireplace -- through a series of smaller metal pipes. Natural gas is billed to the consumer by the cubic foot of gas used. ...
You can use the same tricks as above to calculate an inverter heat pump’s maximum power draw—but it’ll rarely ever run at those top settings. This type of heat pump is designed to run almost constantly, at a relatively low setting. A popular 3.5-ton Mitsubishi cold-climate heat pump...
At night, you take a hot shower thanks to your electric water heater. By the time you're asleep, your home will likely be using the least amount of energy it has used all day. Factors that influence how many watts you need to run your house Electricity usage varies greatly, and there...
On top of the table, I leaned two medium-density fiberboard (MDF) panels at a steep angle against the wall and leaned the cabinet doors and drawer faces against these. I found that when I leaned the doors and drawer faces against the film on the foundation wall, I damaged the film ...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
Using the Nernst equation, one can calculate the EMF produced under a no-load situation: Where E is the Nerstian EMF generated, R is the Universal Gas Constant = 8.31 J*K-1*mol-1, T is the temperature of the cell in Kelvin, F is the Faraday Constant = 96500 Cmol-1, Z is the ...
