Since electricity is energy, it has only one type. Therefore, some electricity cannot be more efficient than others because all electricity is the same. However, some devices use that same electricity more efficiently than others.
* Petroleum provides nearly nine-tenths of all the energy consumed in Hawaii. * Petroleum-fired power plants supply more than three-fourths of Hawaii's electricity generation.
The energy source you mean must be coal, but you seem to have two questions mixed together
depends on source of said electricity, comes from both renewable and non renewable depending on plant and locale, but renewable more often than not (hydro)
By a long distance, using a microwave is more conservative on electricity than by using resistive heating that a stove utilizes.
The cost of production of electricity from a thermal power plant is more than that of the hydroelectricity so the later is more used if both the source are available.

they are used because they save more electricity than the normal ones
more than one cell is multicellular. For example, we are multicellular we have more than one cell.

The lemon does produce more electricity than oranges. BUT in rare cases an orange can produce more electricity than a lemon. But overall its the lemon that's the best.
Nuclear power plants were made in the hope of providing a more efficient source of electricity than is obtained from coal powered plants.
Yes it is possible for a city to have more than one electricity supplier if the city is deregulated, which means more electricity suppliers are competing to gain potential customers.
an outlet has a higher volts than an ordinary static electricity
Hydroelectricity does what all electricity does. Hydro refers to the source of the electricity (generated by moving water) rather than the nature of the electric current itself.
