The conventional electric grid is a network of transmission lines, substations, transformers and more that deliver electricity from power plants to homes and industry. However, with increasing global industrialization and population growth, the grid is being stretched, resulting in the increased likelihood of failures during peak load hours.
In addition, the current grid has difficulty accommodating variable sources of power like wind and solar energy.
In farming businesses, a 20% reduction in energy costs can represent the same bottom line benefit as a 5% increase in sales. Being energy efficient can also enhance a business’s image and reduce its environmental footprint.
This article looks at energy-saving opportunities in the pig farming and dairy industries.
A novel 5MW/15MWh liquid air energy storage system is nearing completion at a landfill waste site near the city of Manchester, England. The demonstration system will be connected to the UK grid to provide balancing services.
The system takes waste heat from the jacket around GE Jenbacher landfill gas engines and uses that waste heat to boost the expansion rate of liquefied air to power a 5MW GE turbine.
A potentially disruptive wind power innovation will begin a week-long trial at a Portuguese air force base before the end of April.
A 16-meter long helium-filled cylinder will rotate creating considerable lift force. A ground-based winch-generator will convert the lift force into electricity. Once the cylinder has reached its maximum height, its rotation is stopped and the module descends to its starting position.
During trials in April 2015, the airborne module will fly below 500m of height .
If presented with a choice of staying with a fixed tariff or moving to a dynamic tariff, will consumers maintain the status quo, or opt for change?
The deployment of smart electricity meters – devices that can read and relay consumption at discrete time intervals – is progressing quickly. Italy has completed its transition. By 2020 France, the Netherlands, Ireland, Norway, the UK and Spain are projected to reach almost 100% deployment.
It’s easy for us to say we support renewable energy. But in practice, what is our willingness-to-pay (WTP) for it?
A key factor in whether a particular country or region is likely to reach its renewable energy objectives – such as the European Union’s goal to achieve a 20% overall share of renewable energy by 2020 – is how willing households are to migrate to its use from conventional energy.
Numerous studies have been carried out to estimate people’s willingness-to-pay (WTP) for renewable energy.
