How it works Electricity comes from the movement of electrons When electrical energy is added to electrons after flipping on a switch they can escape from their normal orbit and flow along a path That’s how we use electricity…letting it flow along a path, called a circuit The easier it is for electrons to break free from their pull of atoms, the better electricity flows and the lower resistance the material has Materials with high resistance, like the light bulb, have fewer electrons to break away meaning they have a stronger pull. These atoms shake up and heat up that’s why we see a flow from the heat as light.

What it can do Electrical energy can be useful when put to work to power a device. Electrical energy often can be converted into…

The reality of Electricity The US is the second largest energy consumer in terms of total use as of 2011. 40% of US energy from all sources is used to generate electricity. Experts predict a 26% increase in the use by 2030. The use of electricity is nearly 13 times greater then that of its use in 1950. The electric power grid has evolved into three large interconnected systems that move electricity around the country.

The future of Electricity The EIA (US Energy Information Administration) projects annual growth in US electricity to average .9% Nuclear Power is becoming the best source of reliable electricity for the future. It is sustainable, affordable, and environmentally sufficient. The problem of exhausting the current method of energy production is the problem for the future. As the rest of the world is catching up with the US industrially, fossil fuel is becoming more scarce. Coal and oil are becoming limited. Natural resources cannot sustain the worlds electricity use any longer. As new technologies are discovered the method for generating electricity in the future will continue to develop.

Disadvantages Advantages In the 20th century electricity started to make a move against standard petroleum-based fuels. Absence of toxic chemicals Electric vehicles can be the cleanest means of transportation and low pollution. The use of renewable energy (sunlight, wind etc) for electricity will lead to far lower CO2 emissions. As more people invest in “green” energy producers, a program known as net metering is growing - where individual home power sources are tied into local electric power plants. Of course, they help many things function and we use it DAILY. Half of the power plants used for electricity still comes from power plants fueled by coal. Pollution, Large amounts of ash released, and carbon in the air. 10 billion tons of carbon dioxide used annually. It is expensive for both building power plants and producing electricity. There is no way of storing unused electricity that the plant produces. Every year 1,000 US citizens die to electrocution and electric shock.
