Answer 2

1. without access to energy

2. uranium-235.

3. nuclear power.

4. 25%

5. all of the above .

6. carpooling.

7. fusion.

8. disposed of in the ocean

Step-by-step explanation:

• About 1/5 of the population lives without the energy supplies in the world.

• The use of U-235 isotope is commonly done for the generation of energy form the fission reaction.

• The US consumes about 25% of the world's energy resources as it uses mostly efficiently technology.

• The least impact on the environment is from nuclear power as its pollution-free.

• Carpooling is the best option to reduce vehicles and save money.

• Most of the sars process fusion of H2 inside there systems like the sun.

• Nuclear radioactive waste is deposited safely in the ocean's trenches.
