Great response! Thanks for the invitation to correct. I'll mark with an asterisk(*) the corrections: In my opinion electric vehicles are a good option for all of *us. We can take care of the environment, and also it can be * cheaper *. If we use energy from the sun to produce electricity, it would be almost free transportation. So, I think it is smart! Explanation: in this case, cheaper is a comparative adjective and we can be more efficient with the language by using the 'to be + adjective' formula (for example, 'I am + happy', 'It is + slow')

In my opinion electric vehicles are a good option for all of as. We can take care of the environment, and also it can be at cheaper cost. If we use energy from the sun to produce electricity, it would be almost free transportation. So, I think it is smart!
