paragraph 2: wind turbines
the most visible and common
important resource
wind power
we need great energy which not add Global warming
summary: wind power is important resource which provides large amounts of energy to meet human needs
important
population growth
provide power for up to homes
wind turbines = common
summary: as a response to growing population, wind power is a curial and promising /potential clear source of energy, and wind turbines are the most common way to harness power of the wind.
problems of traditional wind turbines
expensive
limited locations of wind turbines
not practical to built high turbines
however, conventional wind turbines pose some difficulties/represent a big challenge/have some problems such as high cost, limited locations for
energy kite (feature)
idea from kite
large circles up to 1,000 feet
stronger and more consistent
like turbines and generate in a similar way.
energy kite (Griffith's invention)
comparing with traditional turbines more advantages
take up less land
lighter: from plastic which is cheap
also generate more than twice wind power
more productivity
