The Greeks first discovered electricity about 3000 years ago. Its name came from the word “elektron”, which means amber. Amber is the yellow, fossilised rock you find in tree sap. The Greeks found that if they rubbed amber against wool, lightweight objects (such as straw or feathers) would stick to it.

electric (adj.) Meaning “charged with electricity” is from 1670s; the physical force so called because it first was generated by rubbing amber. In many modern instances, the word is short for electrical. Figurative sense is attested by 1793. Electric light is from 1767.

Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word “electricity” is sometimes used to mean “electrical energy”.

1a : a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons. b : electric current or power.

Electricity is a form of energy and we need it for just about everything! Almost all of our modern conveniences are electrically powered. Electricity is what lights up our classrooms, heats our homes and lets us listen to our favourite music. You are using electricity right now by using your computer to read this.

Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. ​Kinetic energy is defined as the energy of a moving object.

People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems. Direct use of electricity by all end-use sectors was about 0.14 trillion kWh, or about 4% of total electricity consumption.

What Uses the Most Energy in Your Home?

• Cooling and heating: 47% of energy use.
• Water heater: 14% of energy use.
• Washer and dryer: 13% of energy use.
• Lighting: 12% of energy use.
• Refrigerator: 4% of energy use.
• Electric oven: 3-4% of energy use.
• TV, DVD, cable box: 3% of energy use.
• Dishwasher: 2% of energy use.

The answer to this question is a resounding yes! Electricity is all about the movement of charged particles and the electromagnetic force. As far as I know there is nothing we cannot theoretically predict about such systems.

Options for generating your own electricity include: photovoltaic (PV) systems. wind turbines. micro-hydro systems.

• Static Electricity. Static Electricity is nothing but the contact between equal amount of protons and electrons (positively and negatively charged subatomic particles).
• Current Electricity. Current Electricity is a flow of electric charge across an electrical field.
• Hydro Electricity.
• Solar Electricity.

According to the U.S. Energy Information Administration, most of the nation’s electricity was generated by natural gas, coal, and nuclear energy in 2019. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power.

energy of the sun

These are the top 10 energy sources:

• Tidal Energy.
• Wind Energy.
• Geothermal Energy.
• Radiant Energy.
• Hydro Electricity.
• Compressed Natural Gas.
• Solar Energy.
• Nuclear Energy.

There are five major renewable energy sources

• Solar energy from the sun.
• Geothermal energy from heat inside the earth.
• Wind energy.
• Biomass from plants.
• Hydropower from flowing water.

There are posters for all of the types of energy: mechanical, kinetic, potential, gravitational, thermal, chemical, electrical, light, radiant, sound, and nuclear.

There are two sources of energy: renewable and nonrenewable energy.

Examples of this are electricity and hydrogen. We call these two man-made forms of energy “energy vectors”, because both of them enable energy to be carried and can then be converted back into any other form of energy.

People use energy to walk and bicycle, to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, to light our homes and offices, to manufacture products, and to send astronauts into space.

Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth. Our energy choices and decisions impact Earth’s natural systems in ways we may not be aware of, so it is essential that we choose our energy sources carefully.

Energy is an essential part of our daily lives! We use energy to heat and cool our homes, schools, and businesses. We use energy for lights and appliances. Energy makes our vehicles go, planes fly, boats sail, and machines run. All living things need energy too.

Energy comes in six basic forms: chemical, electrical, radiant, mechanical, thermal and nuclear.

Electricity and natural gas are the most-used energy sources in homes

• electricity—all types of energy end uses.
• natural gas—space and water heating, clothes drying, cooking.
• heating oil—space and water heating, clothes drying.
• LPG/propane—space and water heating, clothes drying, cooking.
• kerosene—space heating.

31 Ways to Conserve Energy & Save Electricity

• Turn your refrigerator down.
• Use energy-efficient light bulbs.
• Clean or replace air filters.
• Do full loads.
• Air-dry dishes and clothes.
• Cook using the right-sized burner.
• Cut down on air leaks in your home.

The highest energy content fuel is hydrogen, which is also the simplest chemical component in existence. Gasoline, which is derived from refining crude oil, contains much more energy than coal (twice than the lower grade bituminous) or wood (three times).
