hydro electricity is better than normal electricity because it is cheaper.
Yes. At normal temperatures copper conducts electricity better than almost any other metal; silver is slightly better.
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.
A difficult question because a company that makes hydro electricity would not sell it any cheaper than conventional electricity. It needs oil to be a lot more expensive than the present glut price for hydro electricity to be economic.
nuclear is a type of electricity
Hydroelectricity is often favored over thermal electricity due to its lower greenhouse gas emissions and cleaner environmental impact. Hydroelectric plants utilize a renewable resource (water) and have lower operational costs compared to thermal power plants that rely on fossil fuels. Additionally, hydroelectric power is more reliable and consistent, as it is not subject to fuel price fluctuations.
Hydroelectricity emits far fewer pollutants (including carbon dioxide) than burning coal.
"Pure Water" is non-conductive, it is the minerals and salts in the water that allow it to conduct electricity; and that is why you get shocked. Because water in its normal state will conduct electricity (in most cases better than electrical wires).
That cannot be said with certainty. In the year 2300, there may be more buildings than now. A lot of electricity will come from hydroelectricity or geothermal energy.
Lemon battery is better than real electricity from power plant. Lemon battery saves money than paying electricity bills per month.
Silver
Most houses still use electricity for energy but it is better to get hot water/solar panels to get rid of your electricity bill. Though you'll need more than one to completely dissolve it.
No - copper is a better conductor than nickel.
