Worldwide, political framework reaffirmed sustainable development as a central element of the international agenda and give a new impetus to the practical application of the global measures to combat the negative effects of human actions and for the environmental protection. Since mid 2010, petrol consumption in the transport sector has increased at a higher rate than in other sectors. The transport sector generates 35% of the total CO2 emissions. In this context, strategies have been adopted to use clean energy, ...

To address the global energy problem, energy from the solar source remains the most encouraging solution for buildings with a difficult-to-achieve goal such as achieving zero net energy consumption. In a solar thermal system, integrated solar collectors in buildings can convert the absorbed solar energy into thermal energy and can be better exploited in an area of the facade, while acting as an integral component of the building envelope, with good sun exposure. The aesthetic character and functionality of this te...

In remote, hard-to-reach areas, renewable energy resources such as the sun or wind are available and can be used to produce green electricity at competitive prices. The disadvantage is that we do not always have the source of energy available (sun at night or continuous wind). This disadvantage can be overcome by using hybrid combinations of two or more renewable energy sources together with the storage of the energy produced, thus ensuring the supply of electricity at very good performance levels and with low cos...

In the current global context where we talk about the depletion of conventional fuel resources and their impact on the environment, we find that it is necessary to integrate renewable energy sources/resources in new constructions, but also adapt existing constructions in order to reduce energy consumption. This article presents a system with solar thermal collectors combined with PCM phase change materials. During operation, some of that thermal energy may be diverted to a storage system where it is maintained for...
