Building operation faces great challenges in electricity cost control as prices on electricity markets become increasingly volatile. Simultaneously, buildi
Ok, the sun is still in the sky, but its late enough that I am going to declare November over now, and blog about my generation from my solar farm. First here is the exciting main chart thing: So thats 34.2 MWh, or to put it in rooftop-solar or home-energy terms, 34,248kwh of...
Plus of course we can’t electricify the whole economy. The govt should treat the public as adults and publish the actual numbers for discussion. They are likely to be we need a 3-5x increase in electricity output, so then we need to see how that electricity will be generated, what ...
If you are road traveling, and fast charging then expect the rip-off, around 60 cents Kwh in public networks that puts it a little above the average cost of a 2.0 diesel car, or around 30 cents Kwh in the fantastic Super Charger Tesla network which puts it a bit below the average cos...
Given that the unit price is closer to €500 per kWh [26], a battery bigger than 20.7 kWh will not be profitable. With a very low interest rate of 1%, the same payback period will, of course, allow a bigger battery. Considering a €200 battery price per kWh, the battery size can ...
Figure 3. Chart of the four different analyzed scenarios. In the scenarios, the cell fault rate and the number of packs with faulty cells are the same. The scenarios aim to compare the impact on repurposing costs and the buying price when the battery packs must be disassembled at the modu...
most energy-intensive sectors, particularly iron, crude steel and non-ferrous metals. Despite this increase, the growth of China's energy demand in 2017 was still significantly slower than its 10-year average, and its rate of decline in energy intensity was more than twice the global av...
