Renewable Energy and the Environment

The rush for renewable energy, as an alternative to energy from fossil fuels, generates a number of problems. This paper proposes to investigate domestic energy production using waterfalls. The country has a tradition of harnessing water power by building hydroelectric crowned with success. To these were added in recent years, small hydropower plants (SHP)whose beneficiaries aim to tap the energy of mountain water courses. The amount of energy produced in the country, which has water source, covers about a third of necessary. Is it a renewable energy with minimal environmental impact? Amid legislation and especially of taxation that favors the construction of such SHPs the number of such projects has exploded, although at the same amount of electricity produced an SHP has a 5-8 times higher impact on biodiversity, compared to a hydroelectric dam with. The impact that these have on the environment (SHP) is underreported. We present in this paper how the intervention works in the minor bed for installing water abstraction and adduction results in reduced water flow rate, to change the morphological characteristics of the river beds, the impaired quality of surface waters, and not least to the deterioration of ecosystems of river beds. The case studies that will be presented will focus on SHP Capra in Fagaraș Mountains where deforestation were not the only danger, and SHP Nera, project that would be carried out in the vicinity of the protected area Nera and was provisionally blocked.
