File Scrub 1 ::::: EE ... about_home-basics Energy is the ability to do work Energy comes in different forms: Heat (thermal) Light (radiant) Motion (kinetic) Electrical Chemical Nuclear energy Gravitational People use energy for everything from making a jump shot to sending astronauts into space. There are two types of energy: Stored (potential) energy Working (kinetic) energy For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play. Energy sources can be categorized as renewable or nonrenewable When people use electricity in their homes, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant on a river, to name just a few sources.
Energy sources are divided into two groups: Renewable (an energy source that can be easily replenished) Nonrenewable (an energy source that cannot be easily replenished) Renewable energy. Forms of Energy. Energy forms are either potential or kinetic. Potential energy comes in forms that are stored including — chemical, gravitational, mechanical, and nuclear.
Kinetic energy forms are doing work — like electrical, heat, light, motion, and sound. File Scrub 1 ::::: EE ... about_forms_of_energy-basics What is energy? Energy makes change possible. Energy moves cars along the road and boats through the water. Energy bakes a cake in the oven, keeps ice frozen in the freezer, and lights homes. Scientists define energy as the ability to do work. Forms of energy There are many forms of energy, but they can all be put into two categories: Potential energyKinetic energy. Sources of Energy. File Scrub 1 ::::: EE ... about_sources_of_energy-basics We use many different energy sources to do work. Energy sources are classified as renewable or nonrenewable. Renewable and nonrenewable energy can be converted into secondary energy sources like electricity and hydrogen. Most of our energy is nonrenewable In the United States, most of our energy comes from nonrenewable energy sources.
These energy sources are called nonrenewable because their supplies are limited. Use of renewable energy is growing Renewable energy sources include biomass, geothermal energy, hydropower, solar energy, and wind energy. How are secondary sources of energy different than primary energy sources? Electricity and hydrogen are different than other energy sources because they are secondary sources of energy.
In Homes. File Scrub 1 ::::: EE ... us_energy_homes-basics In Homes Basics The ability to heat and cool is one important accomplishment of modern technology. Our ovens, freezers, and homes can be kept at any temperature we choose, a luxury that wasn't possible 100 years ago. But keeping our homes comfortable uses a lot of energy. Lighting is also essential to a modern society. Compact fluorescent bulbs, or "CFLs," have made inroads into home lighting systems in the last few years.
Appliances such as refrigerators, washing machines, and dryers are also more energy efficient than they used to be. The amount of energy we use in our homes mainly depends on the climate where we live and the types and number of energy consuming devices we use. Videoabout changes in home heating.) The number and variety of ways we use energy in homes is changing rapidly. It is increasingly common for homes to use multiple televisions and computers.
