Policies to incentivize the adoption of renewable energy sources usually offer little flexibility adapt heterogeneous benefits across locations. We evaluate geographical misallocation solar photovoltaic installations and their relation with uniform nature subsidies. estimate dispersion marginal from production in Germany compute social private optimal reallocations residential keeping total cap...

nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  hence, many of the correlations and legislations of a country are affected by it. since iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. but as oil and gas sources are non-renewable ones and cannot be replac...

Evaluation of the reliability parameters in micro-grids based on renewable energy sources is one of the main problems that are investigated in this paper. Renewable energy sources such as solar and wind energy, battery as an energy storage system and fuel cell as a backup system are used to provide power to the electrical loads of the micro-grid. Loads in the micro-grid consist of interruptible...

Energy harvesting – the collection of otherwise unexploited energy in the local environment – is attracting increasing attention for the powering of electronic devices. While the power levels that can be reached are typically modest (microwatts to milliwatts), the key motivation is to avoid the need for battery replacement or recharging in portable or inaccessible devices. Wireless sensor netwo...

Sustainability of current energy policies and their mid-term outlooks are investigated. First, an overview is given about the trend of global energy demand and energy production. The share of energy sources and the geographic distribution of demand are analysed on the basis of the statistics and projections published by major agencies. Sustainability of selected renewable energy sources is then...
