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.

Three main energy sources of the earth'?
The three main energy sources of the earth are solar energy, geothermal energy, and wind energy. Solar energy comes from the sun, geothermal energy is generated from the Earth's internal heat, and wind energy is derived from the movement of the atmosphere.
How can cities improve air quality?
Cities can improve air quality by implementing policies and initiatives such as promoting public transportation, increasing green spaces, enforcing emissions regulations, and encouraging the use of clean energy sources.
What is a another name for renewable energy source?
alternative energy
How does energy enter the Earth system from internal sources through convection and from external sources through radiation from the Sun?
Energy from internal sources enters the Earth system through convection as heat is transferred from the mantle to the surface through the movement of molten rock. External energy from the Sun enters the Earth system through radiation, with sunlight being absorbed by the Earth's surface and converting into heat energy. Both processes play a crucial role in driving the Earth's climate and geological processes.
Energy sources other than fossil fuel are called what kind of resources?
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
What are the sources of kinetic energy?
Movement of any sort involves kinetic energy.
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.
What provides the energy that water needs to evaporate?
These energy sources are the movement of water molecules and the temperature.
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.
How has the mix of energy sources changed in the last 50 years in the production and consumption?
Figure out the answer by yourself. :)
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 :)
Where does energy originates from?
Energy originates from various sources such as the sun, which provides solar energy, as well as the Earth's core, which produces geothermal energy. Other sources include fossil fuels formed from organic matter, nuclear reactions, and the movement of wind and water.
What are three sources of energy that will not run out?
Three sources of renewable energy that will not run out are solar power, wind power, and hydropower. These sources rely on natural and continuous processes like sunlight, wind movement, and water flow, making them sustainable for the long term.
Does wind store chemical energy?
No, wind energy is a form of kinetic energy generated by the movement of air molecules. It is not stored in a chemical form like some other types of energy sources.
What is the form of energy of familiar objects and machines?
Familiar objects and machines can have various forms of energy, such as electrical energy (from batteries or power sources), mechanical energy (from movement or stored in springs), thermal energy (from heat sources), and potential energy (stored energy based on position or configuration).
