Question

why is energy needed? how can we conserve energy resources? explain in three points.​

Answer 1

Answer:

Energy is needed because:

 1. The economic development of any country relies on the energy resources it has. 

2. All sectors of the economy-primary, secondary and tertiary require energy as inputs. 

3. The consumption of energy resources has been increasing over time as development is increasing. We can conserve energy resources by: 

1. Planning should be done for developing a sustainable path of energy usage. 

2. Energy conservation should be promoted at group and individual level 

3. Renewable energy like solar power must be used more.

Answer 2

Answer:

Most of our energy use comes from fossil fuels like petroleum and coal that provide electricity and gas to power our growing energy needs. These resources are non-renewable which means that we will eventually run out. Conserving energy not only helps to conserve resources but also translates into financial savings.
