It is only a short amount of time when this world will not be livable for any living creature to live on, causing us to maybe relocate somewhere else like Mars, but it is very ridiculous because we are just trying to avoid the problems that we have disturbed the environment’s life cycle. An important aspect to pay attention to is our energy crisis. With our energy crisis getting more intense, our world needs to consider using renewable energies. We need to consider using solar, nuclear, bio-fuel, wind, tide, and other renewable energies. Just like what MacKay says we need to say yes to renewable energy not like what we have been doing for a long time saying no.
Something interesting that MacKay brought up in Sustainable Energy - Without the Hot Air was that we could put solar panels in the Sahara Desert to help send solar power to energize all of Europe. So much solar energy could be generated from the Sahara desert that it could power the whole world. In fact there is already being propose by a company called Desertec. This could be an important project that could cut down Europe’s Carbon Footprint down significantly. But there are some concerns about having this project come through. It brings up a reoccurring topic that Europe and other Western countries have been relying on Africa for their resources. A specific event that could be remembered is when Belgium had control over the Congo Free State. It was only Belgium that had any benefit from their control over the Congo. Congo ended up not benefitting at all, but were being tortured, killed, or harassed. The Desertec Project has a similar aspect that Europe will benefit but Africa will not (but there will not be any tortured, killed, or harassed).
Even though it seems that there will not be an even outcome, there is a way to help benefit Africa. There could be a factory where citizens of Africa could work in, so people could have jobs and get paid. Also instead of having Europe have all the power, it could have some power be distributed to some parts of Africa. It is important that we do use renewable energy, but not make the same mistakes from the past.
