Sustainable energy by Mind Map: Sustainable energy

1. Renewable Energy defined

1.1. • Use energy sources that continually replenished by nature

1.1.1. sun

1.1.2. wind

1.1.3. nature

1.1.4. Earth heat

1.1.5. plants

2. Important of renewable energy

2.1. • As substitute from usage of fossil fuels

2.2. • Safety concern

2.3. • Reduces waste disposal problem

2.4. can save money and stregthen our energy security

3. Types of Renewable energy

3.1. Hydropower

3.1.1. Convert the energy in flowing water into electricity
