I am never sure what is meant by 'alternative energy'. Does it include nuclear and hydro for example? The best I can do is give a breakdown as follows,(for 2006) and you can decide what you call the alternatives.
Coal + oil + natural gas 70.8 percent. Hydro 7.0 percent. Nuclear 19.4 percent. Wind 0.7 percent. Solar 0.1 percent. Incinerators 0.3 percent. Geothermal 0.3 percent. Biomass 1.3 percent.
I expect wind and solar are now a little higher than in 2006
The word is galvanism. It means electricity produced by chemical action.

Nuclear power plants typically operate at an efficiency rate of around 33-37%. This means that about one-third of the energy produced by the reactor is effectively converted into electricity.
The definition of the word 'cogeneration' means that electricity is produced from either an engine or power station and that the electricity is turned into useful heat.
that means that 69.8 grams will be produced when the theoretical yield is 100 grams.
Electricity is a form of energy that is found in nature (such as lightning) and can be produced by man through various means like generators and batteries.
The Hoover Dam generates 4.2 billion kW/h of electricity each year. The United States produced about 4.151 trillion kW/h of electricity in 2010. This means the Hoover Dam produced about .101% of the total US power.
Hiko means electricity. Uira also means electricity in Maori.
In this context, to save electricity is "not to use it" rather than to "save it somewhere safe". The primary reason for consumers is that by not using electricity, you will not have to pay for it. The secondary reason is that if we, as consumers, use less electricity then the suppliers will not have to produce so much either which, in turn, means that less greenhouse gases will be produced at electricity generating stations.

Multiply 74 by 3...======================Another contributor offered an alternative, more detailed approach:-- recall that 74 percent is 0.74-- recall that "of" means "times"-- multiply 0.74 times 300-- get 222
When the electricity supplying an electromagnet is switched off, the magnetic field produced by the electromagnet disappears. This means that the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.
