One aim of the RESFOOD project that has not yet been cited in the previous posts is the maximization of the resource productivity. An example of this aspect is the use of solar panels. Solar energy is a renewable energy that is in fact free but you have to invest first in solar panels. But what are the pros and cons from solar panels? I found a list of the advantages and disadvantages on the internet: http://energyinformative.org/solar-energy-pros-and-cons/

In the list are more advantages as disadvantages. First I will give a short summary of the advantages. Solar energy is renewable what means that we cannot run out of it and there is plenty of it. That makes that it is also sustainable because we can never over-consume. Moreover it causes less pollution than other conventional energy sources. Not only the countries that are closest to the equator can use solar energy, it is available all over the world. In addition it reduces the electricity costs because sometimes homeowner produces more electricity than they consume.

However there are still some advantages. The most abundant disadvantage is that it is expensive. Firstly the solar panels are very expensive because sometimes they require materials that are expensive and rare in nature. It is an investment but after a certain time you will take advantage of it. Secondly, the energy storage is expensive. Besides the cost it is also an intermittent energy source because the sunlight is limited at certain times and it is not completely pollution free.

Well, I am already convinced of the use of solar panels. But what do you think about solar energy?
