Petite aide en Anglais :)

Bonjour à tous,
Je suis étudiant et je dois rédiger un résumé et un commentaire à propos d'un article du "Times" à propos de voitures écologiques(en particulier d'une nouvelle sportive de cher Lotus).
Pourriez-vous vérifier l'orthographe et la tournure de mes phrase?
Merci d'avance.

Summary:
Lotus has recently created a new economic car made from weeds. Because nowadays, it is very important to think about green energy.
This Lotus is made from non-traditional materials as wool and hemp. A big part of useful energy is provided by solar panels situated on the roof of the car. And the paint used is cheaper and more environment friendly than the ordinary one.
Moreover, a lot of materials come from local suppliers. So, there are no costs for the transport of the materials. And the amount of CO2 produced during the transport is reduced.
Lotus has already made another environment friendly car before: an electric sport car, the Tesla Roadster. Even if it is a “green” car, it gives a top speed of 200 km/h and it is very popular in America.
These cars prove us that progresses can easily be done to reduce CO2 emissions. Lotus also wants to reduce its energy consumption by searching alternative fuels, and by using wind turbines to produce electricity to power all their industry.

Comments:
I think that we all should start to drive “green” cars in the future. This Lotus is a good example of car witch combines power with environment–friendly materials.
There are a lot of economic cars nowadays, like the well-known Toyota Prius and Honda Insight. And from a green point of view, a green car is a great deal. Because it saves you considerable money
The only disadvantage of this kind of cars is that the cost is higher compared to conventional sportive cars. But, the hybrid car can counter this disadvantage by allowing consumers to save money in a long term basis.
Moreover, this car has high performances like other sportive cars. Buy with less emissions of CO2 than other sportive cars.
But there are still a lot of things to do to be more environment-friendly.
