What are the types of electricity?
There are two types of Electricity, Static Electricity and Current Electricity. Static Electricity is made by rubbing together two or more objects and making friction while Current electricity is the flow of electric charge across an electrical field.
What are two main types of electricity?

What is the best type of electricity?
Although there are many types of energy, the most efficient forms are renewable: hydro-thermal, tidal, wind, and solar. Solar energy has been proven to be the most efficient and effective among renewable energy sources for home and commercial use.
What is the most powerful thing in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
Do we need nuclear power?
Nuclear advocates claim nuclear is still needed because renewables are intermittent and need natural gas for backup. However, nuclear itself never matches power demand so it needs backup. Thus, subsidizing nuclear would result in higher emissions and costs over the long term than replacing nuclear with renewables.
Is there a future for nuclear power?
In the U.S., nuclear power plants have generated almost 20 percent of electricity for the last 20 years. Most of the nuclear plants operating today were designed to last 25 to 40 years and with an average age of 35 years, a quarter of them in developed countries will likely be shut down by 2025.
