Coal is in short supply and nuclear energy is both expensive and potentially harmful to the environment. The solution could be in the use of renewable.

Current Electricity. Let’s review what we know about electric charges: Objects are made of negative and positive charges Objects are made of negative.

 Source of voltage difference ◦ Battery, outlet  At least one device that uses the electrical energy ◦ Radio, microwave, clock, etc  Conductor that.

P  A way of drawing an electric circuit using standard symbols  Some symbols require you to identify the positive and negative terminals e.g.

San Diego, Russia, Cameron.  West Virginia, like Russia, is rich in natural resources such as coal and gas. These two are our main sources of energy.

Electrical energy in designs

Electrical energy is used in many designed solutions. 1. 2. 4. 3. 5.

Electricity flows through a circuit to make it function the way the designer wants it to. 6.

There are many sources of electrical energy that can be used in designs. mains power batteries 2. 1. solar cells generators 3. 4.

These can have limitations and benefits for designers. Why are batteries useful for a torch but a lamp is plugged in and uses mains power?

Some sources are more sustainable than others. wind energy solar panels coal power station 2. 1. 3.

How can sustainable sources of electricity be used in designs?
