Renewable energy:


Renewable energy is generally defined as energy that is collected from resources which are naturally renewed on a human timescale, such as sunlight, wind, tides, waves, geothermal heat, hydrogen, marine and biomass. This type of energy has many benefits such as renewability, energy production with a high efficiency, decentralized and distributed production of energy, clean energy and, alleviating power generation challenges. Nearly a fifth of global total final energy consumption is met by renewables, by 2015 (Fig1).

The three main drivers for increasing the deployment of renewable energy which have gained more importance in the recent years are the rise in the energy demand, the depletion of fossil fuels and climate change.

Inappropriate consumption of fossil fuels, leads not only to financial losses, but also to many other irreparable damages to the planet. The crisis of Greenhouse gas emissions and climate changes in different countries around the world has made everyone implement environmental rules and regulations, in order to achieve a sustainable development; besides, they have made changes in their national proceedings, so as to find alternate and renewable sources of energy, diversify their energy mix and provide the ground for using the renewable energy. Renewables captur two-thirds of global investment in power plant to 2040 as they become, for many countries, the least-cost source of new generation (Fig2). Renewable energy in accordance with major energy policies of the country, and with the purpose of gaining independence from oil products, bring many benefits for the country through diversifying the country’s energy mix, enhancing the security of production and distribution of energy, protecting fossil fuels, providing knowledge-based job opportunities and strengthening the country’s passive defense. Currently, more than 200MW of renewable installed capacity have been operated in iran, which is not considerable, but the growth rate is promising. According to the energy macro policies of the country and the section 7 of the rectification of consumption patterns act, the priorities of the country’s comprehensive scientific plan, and other plans and policies of the country, knowledge-based development of the renewable energy has been prioritized. 

In order to the development and deployment of renewable energy’ technologies, innovation is necessary; so that these technologies can move from research and development level to commercialization. Eliminating the obstacles on the way of development of renewable energy’ market plays a critical role in the deployment of renewable energy in the future.
