The renewable-energy industry is the part of the energy industry focusing on new and appropriate renewable energy technologies. Investors worldwide have paid greater attention to this emerging industry in recent years. In many cases, this has translated into rapid renewable energy commercialization and considerable industry expansion. The wind power, solar power and hydroelectric power industries provide good examples of this.
In 2020, the global renewable energy market was valued at 881.7billionandconsumptiongrew2.9EJ.Chinawasthelargestcontributortorenewablegrowth,accountinganincrementof1.0EJinconsumption,followedbytheUS,Japan,theUnitedKingdom,India,andGermany.InEurope,renewableconsumptionincremented0.7EJ.Net−zeroand100In2020,renewablesourcesincorporatedintoenergyconsumptionatitsfastestrateintwodecades.During2006/2007,severalrenewableenergycompanieswentthroughhighprofileinitialpublicofferings(IPOs),resultinginmarketcapitalizationnearorabove1 billion. These corporations included the solar PV companies First Solar (USA), Trina Solar (USA), Centrosolar (Germany), and Renesola (U.K.), wind power company Iberdrola (Spain), and U.S. biofuels producers VeraSun Energy, Aventine, and Pacific Ethanol.
Renewable energy industries expanded during most of 2008, with large increases in manufacturing capacity, diversification of manufacturing locations, and shifts in leadership. By August 2008, there were at least 160 publicly traded renewable energy companies with a market capitalization greater than 100million.Thenumberofcompaniesinthiscategoryhasexpandedfromaround60in2005.Some150 billion was invested in renewable energy globally in 2009, including new capacity (asset finance and projects) and biofuels refineries.

This course presents an overview of (i) the current energy system and uses (ii) the main principles of conventional and renewable energy technologies and (iii) the most important parameters that defin
100% renewable energy means getting all energy from renewable resources. The endeavor to use 100% renewable energy for electricity, heating, cooling and transport is motivated by climate change, pollution and other environmental issues, as well as economic and energy security concerns. Shifting the total global primary energy supply to renewable sources requires a transition of the energy system, since most of today's energy is derived from non-renewable fossil fuels.
