(7) through different technologies, such as solar cells, scientists have learned to use the suns radiation to create electricity. (8) solar energy is both inexhaustible and clean. (9) the major limit to this alternative source is that equipment is expensive. (10) developing a cost - effective way to harness the power of the sun will be a significant development in solving our energy crisis. read the following sentence researchers are working on batteries that store energy generated from solar power, so it could be used at all times. where in the essay should the above sentence be added and why? after sentence 10 to serve as a conclusion after sentence 5 as part of the claim after sentence 6 to support the topic sentence after sentence 9 to support the counterclaim

Sentence 9 presents the problem of high - cost solar equipment. The added sentence about researchers working on solar - power - storing batteries addresses a potential solution to the limitation (high cost due to equipment) mentioned in sentence 9. It supports the counter - claim (that solar energy has limitations but solutions are being developed).

Answer:

after sentence 9 to support the counterclaim
