Energy harvesting is a new promising research area for portable electronics. Portable electronic devices have been typically limited by the finite lifetime and size of the internal batteries. This has been a constant conflict and tradeoff between battery size and device capabilities. For instance, cardiac pacemaker lifespan is mostly limited by battery size, which occupies at least half the ava...

Almost one-quarter of the world's population has basic energy needs that are not being met. Efforts to increase renewable energy resources in developing countries where per capita energy availability is low are needed. Herein, we examine integrated dual use farming for sustained food security and agro-bioenergy development. Many nonedible crop residues are used for animal feed or reincorporated...

The focus of the European Union (EU) energy policy is on the promotion of low-carbon technologies and renewable-energy sources. In pursuit of this target, EU countries are setting up adequate support schemes (e.g. feed-in-tariffs). This is giving rise to different generation technologies and growing share of small scale generation in power networks. The paper deals with the impact of distribute...

Due to disperse nature of renewable energy resources (RES), electricity generation is often taking place in small scale but main drawback is power quality. So to improve power quality issues, integration of renewable energy into the utility grid can be done either at transmission level or the distribution level depending on the scale of generation. The renewable resources like solar energy, win...

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...

small-scale dairy farming in bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...
