We are presently witnessing an energy revolution due to continuous technological innovations and an increasing political and public awareness for the need to find alternative energy sources. Flexibility and adaptability to different environmental conditions, economic incentives and an increasing variety of types have led to the exponential growth of the market for photovoltaic systems. The spreading of projects across Europe, however, causes the loss of agricultural land and raises concerns about the visual impact of these installations, factors which are influencing the current debate on energy policy. On the other hand these projects open new design possibilities related to environmental compensation measures. Lately we are seeing attempts to employ innovative solar collection systems in infrastructure design, redevelopment of abandoned industrial areas, and projects of greenhouses and farm buildings. The current technological research offers interesting project proposals that mediate between the natural and the artificial.
