2. Nuclear energy
3. Geothermal power
4. Solar
5. Wind
conservation of energy is very important in current situation of energy crisis. Efficient utilization of energy sources must be one of the top priority of nations.
1. Procurement of alternate sources of energies to reduce dependence on convectional sources of energies.
2.vehicle running on electric and hydrogen fuels should developed so that sources of coal and petroleum are conserved.
3. Production of solar and wind energies should be on large scale so that their cost become cheaper and available for common people
Explanation:
The planets Mercury and Venus , present inside the Earth's orbit appears to move with smaller epicycle sizes than the planets outside the orbit of the Earth i.e. , Mars , Saturn and Jupiter .
Therefore , the planets Mercury and Venus sometimes appears between the Planet Earth and the Sun .
For planets , Mars , Saturn and Jupiter , the epicycle orbits are much larger and is centered around the sun .
Therefore , these planets appear on the other side of the Earth from the sun and never between the earth and the Sun .
