Question

Rosa listed some advantages and disadvantages of using renewable resources. Which best describes Rosa’s error?A. Wind does not easily generate a lot of electricity. B. Wind is a very reliable energy resource. C. Geothermal energy causes a lot of air pollution. D. Geothermal energy is available everywhere.

Answer 1

Answer: Rosa's errors were options

A: Wind does not easily produce a lot of electricity.

C: Geothermal energy causes a lot wind pollution.

Explanation:

Wind Energy is the use of wind (kinetic energy) to provide mechanical energy and electricity through wind turbines. The wind turbines in a Wind farm ( made up of several wind turbines connected together) are then connected to electric power transmission network to generate electricity to households and grids.

Electricity is measured in Mega Watts (MW); Rosa is wrong because wind energy amounts for a significant percentage of electricity used in some developed worlds and mostly the European Union (EU) at a recorded 270 Giga Watts (GW). It is estimated that by 2020, wind energy will produce 50 percent of energy used by the EU.

Geothermal energy is the thermal energy (temperature of matter) which is gotten from energy generated and stored in the earth. Geothermal energy comes from radioactive decay of materials and the formation of earth.

Rosa is wrong, because Geothermal energy is environmental friendly and does not cause significant pollution. It does not involve fuel to harness its energy which in turn leads to stable electricity prices.

Answer 2

Answer:

The correct answer is option A. Wind does not easily generate a lot of electricity.

Explanation:

Hello!

Let's solve this!

Wind is used to generate wind energy. Wind energy generates electric energy. A large percentage of the energy used comes from the wind. So Rosa is wrong in answer A.

The correct answer is option A. Wind does not easily generate a lot of electricity.
