How the sources of energy for light and movement in cities changed over the last 120 years?

About 120 years ago the insides of buildings were lit by candles, oil lamps and gas lights. Coal and wood were used as fuel or fires to keep the buildings warm in winters. The streets were lit by gas lights. Today, the buildings are lit by electricity. Some buildings have air conditioning powered by electricity to keep them cool in summer. They also have heaters powered by electricity to keep them warm in winter.

Where does the energy from solar wind hydroelectric sources originally come from?
As you will know energy can not be created. Only transferred from one thing from another. Solar energy captures energy from the sun. Wind energy gets it from the kinetic energy making it move. And hydro electric also gets from kinetic energy. But kinetic energy from the movement of the waves.
Introduction on non conventional energy sources?
renewable sources of energy
What energy source is renewable?
Renewable energy sources are Solar, wind, Geothermal, Tidal are prime energy sources
What is the two reasons why alternative energy sources may be important in the future?
· To protect against harmful by-products of major sources of energy · To preserve many of the natural resources that we currently use as sources of energy
What are some good sources of Alternative Energy?
Other than what? Please clarify.Common energy sources (for technological purposes) are fossil fuels (petroleum and coal), nuclear energy, as well as solar energy, wind energy, hydraulic (water) energy, and many others.
What are the sources of kinetic energy?
Movement of any sort involves kinetic energy.
What provides the energy that water needs to evaporate?
These energy sources are the movement of water molecules and the temperature.
How are coal and oil types of energy?
They are not. They are substances which are sources of energy. When you burn them chemical energy is changed to heat and light.
Is the energy acquired by a body because of its motion is called potential energy?
No, energy created from movement is called Kineticenergy. Potential energy is energy created from no moving sources.
Fuels such as the wind and sun that can generate power without being used up?
Wind energy and solar energy are called renewable energy sources. Other renewable energy sources include hydroelectricity (generated by water movement) and geothermal energy.
What are sources of energy that cause atmospheric movement?
I need help with that answer also! Please help! THANX :)
How has the mix of energy sources changed in the last 50 years in the production and consumption?
Figure out the answer by yourself. :)

What are the names of the the nine sources of energy?
Kinetic Energy (movement)Sound EnergyChemical EnergyElectrical EnergyLight EnergyThermal Energy (Heat)Gravitational Potential (The ability for something to drop)Potential Energy (The ability to be a certain energy)Nuclear Energy
How is hydro power converted into electricity?
A turbine spins water creating kinetic (movement) energy. This kinetic energy is changed into electricity through a generator connected to it.
What are Iran's energy sources?

What are the different types of energy you get from the Sea?
Wave action and tidal movement are two sources of possible energy if harnessed by turbines and floats, etc, connected to a bank of electrical generators.
