In this case plants convert light energy (1) into chemical energy, (in molecular bonds), through a process known as photosynthesis. Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy.

Sunlight provides the energy needed to tear apart water and carbon dioxide molecules so they can be rearranged into sugar molecules. Light energy is crucial to the photosynthesis process.

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.

Three Gorges Dam

Most Expensive Electricity by State Hover over any state to see its average price of electricity. Hawaii leads the lot by being the most expensive state for electricity (34.43 cents) while Washington is the cheapest state (9.35 cents).

Across all sectors, Hawaii has the highest electricity rate (29.18 cents), and Louisiana has the lowest electricity rate (7.71 cents)….Annual Average Price. per Kilowatthour. by State.

The United States has cheaper residential electricity than other affluent nations, with the exception of Canada and Norway, which derive high shares of their power from hydroelectric generation (60 percent and 95 percent, respectively).

How Much Electricity Do My Home Appliances Use?

Here’s a breakdown of the biggest energy use categories in the typical home:

• Air conditioning and heating: 46 percent.
• Water heating: 14 percent.
• Appliances: 13 percent.
• Lighting: 9 percent.
• TV and Media Equipment: 4 percent.

55-inch LED TVs are very popular models as main TVs in many homes with 60-inch and even larger models becoming more and more popular as well. Again, their consumption may vary, but generally: – 55″ LED: 60 – 90 watts, on average 80 watts, – 55″ OLED: 90 – 120 watts, on average 105-110 watts.

The energy costs of plugged-in appliances can really add up, and unplugging these devices could save your up to $100 to $200 a year. Another benefit of unplugging your appliances is protection from power surges.
