There has been a growing trend in renewable energy diversification as technology, economics and environmental issues drive the need for alternative energy generation. Harnessing energy from a range of different sources is becoming more and more popular and efficient. One such form is anaerobic digestion; the controlled breakdown of waste matter to produce combustible biogas and nutrient-rich organic by-products. Another is by utilising the sun with the installation of solar parks. This offers a cost-effective way to maximise yield from low-grade agricultural land.
