Wind power production has been under the main focus for the past decade in power production and tremendous amount of research work is going on renewable energy, specifically on wind power extraction. Wind power provides an ecofriendly power generation and helps to meet the national energy demand when there is a diminishing trend in terms of non-renewable resources. This paper reviews the modeli...

Hydrogen, a clean energy carrier with high energy capacity, is a very promising candidate as a primary energy source for the future. Photoelectrochemical (PEC) hydrogen production from renewable biomass derivatives and water is one of the most promising approaches to producing green chemical fuel. Compared to water splitting, hydrogen production from renewable biomass derivatives and water thro...

Low-cost alkaline water electrolysis has been considered a sustainable approach to producing hydrogen using renewable energy inputs, but preventing hydrogen/oxygen mixing and efficiently using the instable renewable energy are challenging. Here, using nickel hydroxide as a redox mediator, we decouple the hydrogen and oxygen production in alkaline water electrolysis, which overcomes the gas-mixi...

Renewable energy is an important topic in China as the country experiences increased wealth and energy demand. Historically, hydropower has been a valuable source of renewable energy production in China, and will continue to be as the Chinese increase hydroelectric facilities by 2020. Using provincial level data from 1980-2010, this paper estimates the relationship between the percentage of hyd...

This paper analyses the impact on renewable energy sources integrated into the Romanian power system on the electrical network operation considering the reduction of electricity consumption with respect to the 1990s. This decrease has led to increased difficulties in integrating the renewable energy sources into the power system (network reinforcements), as well as issues concerning the balance...

fixed feed-in tariff An offer by government or a utility to purchase electricity from renewables producers at a fixed price, regardless of the producers’ costs of production. green (renewables) certificate A certificate, provided by a regulator to renewables producers for specified units of their electricity output; can be traded to other electricity producers who need it to meet their obligati...

The massive and continuous development of renewable energy systems is making it possible to achieve the European goals regarding environment and sustainability. On the other hand, it leads to the progression of significant problems such as low renewable energy density (i), social acceptability (ii), and non-programmability of renewable energy sources (iii). The rural architecture, which is larg...
