Gas electric hybrid heat pumps (GEHHPs) are individual heat pumps consisting of an electric heat pump and a gas boiler. They enable a fully flexible operation of electric heat pumps by supplementing electricity with gas when necessary. In this paper, we construct a cost optimization model of ...
The Chinese government has set long-term carbon neutrality and renewable energy (RE) development goals for the power sector. Despite a precipitous decline in the costs of RE technologies, the external costs of renewable intermittency and the massive inve
Learn how electric vehicles compare to gas powered automobiles in terms of list prices, operating costs, range and miles per gallon.
The main objectives of this project are to design the proper retrofit scenario and to calculate the potential electricity saving, the payback period, and the potential environmental benefits. In this survey the policy for retrofitting the old lighting system with the new energy saving LEDs starts ...
Our guide to understanding your energy use in kW and kWh will help you get greater control of your electricity and gas bills.
The heat production cost of boiler wood pellets, wood chips and straw are lower than 35 EU/MWh. The heat production cost of electrical heat pump is around 37 EU/MWh. The heat price of the boiler straw is the lowest one, below 25 EU/MWh. The heat price of natural gas boilers ...
In general, the cost of charging an electric car like a Tesla is cheaper than the cost of fueling a gas-powered car.
