Is electricity considered an energy resource?
Sometimes, but electricity isn't an energy SOURCE; it's an energy CONDUIT. Electricity is how we get energy from one place to another, and how we use it when it gets there. Electricity doesn't stand still; at least, not naturally. We generate electricity with generators that use some other power source to spin a turbine; a jet engine, for example, or falling water, or steam. The electricity goes through a wire to where we use it by converting it into some other form; light, or heat, or music, or radio transmissions. We can store electricity in a battery, but that's a very inefficient process so far. And the electricity doesn't really do us any good until we convert it into something else.
Is taking shorter showers saving energy?
Obviously. If you use electricity or some other energy source to heat up the water, making the shower shorter will help save energy.
Why is electricity such a usefull source in energy?
Electricity , as a secondary source of energy, is easy to transport and easy to be converted at end energy use point to energy the form needed (as in lighting, heating, industry, transportation, etc.). Electricity by itself as secondary energy source is environmentally clean secondary energy source. Pollution caused by its production depends on the type of the used primary source (coal, oil, gas, nuclear energy, wind, etc.) However, electricity is usually produced in thermal power plants at efficiency less than 50%. So, it is expensive high grade secondary energy source.
What are some examples of how electricity can be converted to other forms of energy?
Electricity is stored as chemical energy when you charge a battery. Electric motors turn electricity into kinetic energy. Electric ranges/ovens/stoves turn electricity into heat energy.
What are some disadvantages of wind energy source?
wind is not friendly to the environment ,as fossil fuels are not burnt to generate electricity.

Electricity is often said not to be a clean convenient source of energy why?
Electricity by itself is fairly clean; but whatever process is used to generate the electricity may cause pollution. You simply don't get electricity out of nothing, you need to convert some other type of energy to electricity.
Why isn't nuclear energy cost effective?
It is not true. The levelized cost of a kilowatt hour electricity from nuclear energy is cheaper than any other source of electricity except hydraulic power in some countries.
Why is electricity commonly used as a source of energy in urban areas?
Because - in some poorer countries, there is no 'mains' supply - meaning that people need to generate their electricity by other means.

Why is solar electricity commonly used as a source of energy in urban areas?
Because - in some poorer countries, there is no 'mains' supply - meaning that people need to generate their electricity by other means.
What are some of the uses of bioenergy?
Bioenergy just means that it comes from biological things. Once you have this energy in some useful form (for example, electricity), you can use it for anything where you can use any electricity from any other source.
What energy source does a car use?
Some use electricity, most use gasoline.

What species could survive without the energy from the Sun?
None, unless you assume there is some other energy source available. All types of life need energy.None, unless you assume there is some other energy source available.
