Solar en ergy is lauded as an in exhaustible fuel source that is polluti on and ofte n no ise free.The tech no logy is also versatile.For example,solar cells gen erae en ergy for far-out places⑷ like satellites in Earth orbit)and cab ins deep in the Rocky Mou ntai n as easily as they can poer downtown(42bui

futuristic cars).

But solar energy doesn rwork at night without a storage device(43such as a battery), and cloudy weater can make the tech no logy un reliable duri ng the day.Solar tech no logies are also very expe n sive and require a lot of la nd area(44to collect the sun ' enerqy) at rates useful to lots of people.

Despite the drawbacks,solar energy use has surged at about 20 percent a year over the past 15 years,tha nks to rapidly falli ng orices and gains in efficie ncy.
