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
• Thats how we use electricityletting 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 thats 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.

Advantages
Disadvantages

• 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.
