Could excess energy produced by an industrial plant be used for nearby residences?
As a city expands, industrial companies that were originally located well outside the city perimeters sometimes now find themselves surrounded by residential areas. This opens up interesting opportunities. For example, an industrial plant often produces lots of low temperature waste heat in its processes; waste heat that could be used by residential districts for heating purposes.
Two Taiwanese authors collated a few hundred case studies on energy management since the 1970s and analysed their potential energy-saving effect.
Energy management systems have been extensively studied for almost 40 years.
The remoteness and small size of many of the world’s islands means an unhealthy dependence on expensive imported fossil fuels, and a corresponding key role for renewables
About 740 million people live on more than 50,000 islands, most of which rely heavily on imported fossil fuels. The Caribbean Islands for example rely on imported fuel for 90% of their energy demand. The cost of energy is thus a huge burden for islands, some of which spend a third of their GDP on fuel imports.
Thousands of schools throughout the world lack basic electrification and hence sub-optimal lighting, heating and modern teaching tools. However, planners, investors and policymakers have a number of tools available to improve energy for education.
Nearly 200 million children in the world attend primary schools that are not connected to any source of electricity. Included in this number are over 80% of the children in Sub-Saharan Africa, more than a quarter of village schools in India, and over half of Peruvian schools.
Levelized Cost of Electricity (LCOE) is generally used to compare individual generating technologies. But what if LCOE was calculated for a hybrid PV + battery + CHP system?
There is nothing new in the idea of using a hybrid system consisting of three energy technologies – solar photovoltaics (PV), batteries and Combined Heat & Power (CHP) – as an alternative to a traditional grid connection. It is just one of many microgrid concepts that are possible.
