Renewables energies industry in the current investment context

Abstract

The current shifts in the global energies market lead the expected change in the long term from traditional energies sources, like fossil fuels, to renewable energies sources, e.g. sun, wind, water, energetic wood etc. The major commitments are: sustainability, productivity, smart energy grids and functional energy systems, industrial ecology, green chemistry, bio mimicry, green nanotechnology. The most important investment criterion relies upon efficiency: energy return of invested energy (EROIE), but there are also other relevant issues such as: policies to support RE, e.g. green certificates, legal issues to exploit resources or the capital costs and operational & maintenance costs. Romania’s best RE potential lies in biomass, hydro and wind, but still is a lot to capitalize on geothermal and solar photovoltaic or in conjoint projects between private investors and authorities, especially in waste incineration power plants.Renewable/green energies, CO2 emissions, EROIE, capital costs, O&M costs
