There are numerous possible applications for hybrid power systems. The most common examples are (1) remote AC network, (2) distributed generation applications in a conventional utility network, and (3) isolated or special purpose electrical loads.
The classic example of the hybrid energy systems is the remote, diesel-powered AC network. The basic goal is to decrease the amount of fuel consumed by diesel generators and to decrease the number of hours that they operate. The first addition to ‘‘hybridize’’ the system is to add another type of generator, normally using a renewable source. (more…)

The term hybrid energy system refers to those applications in which multiple energy unit conversion devices are used together to supply an energy requirement. These systems are often used in isolated applications and normally include at least one renewable energy source in the configuration. Hybrid energy systems are used an alternative to more conventional systems, which typically are based on a single fossil fuel source. Hybrid energy systems may also be used as part of distributed generation application in conventional electricity grid. (more…)

Drying is one of the most important post harvest steps. It enhances the storage life of the crop products, minimizes losses during storage, and saves shipping costs. The drying process is the removal of water from the wet surface of the food. In this process, heat is transferred by convection and radiation to the surface of the produce. This heat raises the temperatures heat and evaporates the moisture from the exterior of the agricultural products, diffusing the interior moisture to the surface and replenishing the evaporated surface moisture.

The continuous availability and affordability of energy and, in particular, electricity supply is an indispensable condition for the working of a well-functioning modern society. This is especially true for advanced industrial or post-industrial societies, where electricity generation provides the services essential for production, communication and exchange. Unsurprisingly, governments of OECD countries are thus concerned with understanding the factors influencing the security of energy and electricity supplies and seek to develop policy frameworks and strategies to enhance them.

Cost–benefit analysis (CBA), also known as benefit–cost analysis, is rooted in applied welfare economics. It is a way of organizing and analyzing data as an aid to thinking. It provides a set of procedures for comparing benefits and costs and is traditionally associated with government intervention and with the evaluation of government action and government projects. The underlying rationale for CBA is rational choice; that is, a rational agent will weigh the costs and benefits of any proposed activity and will only undertake the activity if the benefits exceed the costs.

Would it not be great to be able to produce your own electricity supply at home? The idea of being independently powered up without relying on the utility company is not that far away from becoming a reality. Homeowners are already buying into the idea of using homebuilt wind generators to make their own electricity supply.
But do these homebuilt wind generators work? Homemade wind power systems are a smaller scale version of those gigantic turbines that provide electricity (more…)

Statistics on national production levels and indicators of environmental pressure have been collected during the past few decades (and reconstructed for the more distant past) to document the link between world economic growth and the environment. The theory of world economic growth and economic theories of world natural resources provide explanations and interpretations of the trends as well as methods to assess future developments. The basic approach in most statistical and theoretical analyses is the decomposition of aggregate production function of a nation into, on the one hand, the current state of technology and, on the other hand, the inputs into the national production process. The main inputs are labor (hours worked), capital (produced means of production that can be used over a certain time period), and world natural resources. (more…)
