Cambridge students has found a way to make a solar energy dependent vehicle that could reach speeds of 60 mph using lesser energy than some house-hold appliances (Cambridge). Since the sun the most abundant energy that the earth can have, it is important that we use this energy to substitute for other resources. What the student at Cambridge discovered is a great discovery and can be used to replace petroleum-based vehicle. Having a energy efficient vehicle that produces low carbon is the type of vehicle that we need in the future. Fortunately, the technology has been discovered and the only problem now is how is the car going to be financially available for the public? will this technology be available at low cost and will the public purchase it? The world needs a change and by substituting petro-based vehicle with energy efficient vehicles like the ones at Cambridge is a great way to start.
