We use the same amount of electricity as other homeowners but our bill is much lower,\u201d Kiltorp continued.<\/p>\n<p>The flats are powered by other, renewable energy sources too, making them \u201calmost self-sufficient\u201d, Kiltorp said.<\/p>\n<p>No longer simple modes of transport, the cars now also serve as mobile energy storage units.<\/p>\n<p>In addition, the eight flats have a shared heat pump, which helps manage heating costs.<\/p>\n<p>And they have solar panels on the roofs, combined with stationary storage units that hold any surplus power generated by the solar panels.<\/p>\n<p>The pilot project is a joint enterprise by housing association BRF Stenberg, carmaker Volkswagen and Swedish utility company Vattenfall.<\/p>\n<p>It aims to demonstrate that V2G (Vehicle to Grid) technology can work on the scale of a residential complex.<\/p>\n<p>\u201cWe\u2019re trying to be a source of inspiration for others,\u201d said Boman, who used to work in the vehicle industry.<\/p>\n<p>In Sweden, the technology is also being tested in larger buildings, universities and start-ups.<\/p>\n<p>Gavle University in central Sweden staged a power cut in the middle of a speech there by the higher education minister to demonstrate how its bidirectional chargers worked.<\/p>\n<p>They plugged an electric car in and this kept the premises working for several hours.<\/p>\n<p>\u201cI call this a battery on wheels,\u201d Nicholas Etherden, a lecturer and researcher in energy systems at the university, told AFP.<\/p>\n<p>\u201cCars drive about five percent of the time.\u00a0Ninety-five percent of the time they are standing still in a car park somewhere,\u201d he explained.<\/p>\n<p>\u201cIf we connect them to the grid, we have a resource that will, at any given time, provide more electricity than the amount people draw from the grid at the highest peak times.\u201d<\/p>\n<p>\u2013 \u2018Enormous potential\u2019\u00a0\u2013<\/p>\n<p>On average, a vehicle battery can cover a household\u2019s needs for between five and seven days before running down.<\/p>\n<p>\u201cSo we have enormous potential,\u201d the researcher said.<\/p>\n<p>Wider adoption of the model still faces several obstacles.\u00a0<\/p>\n<p>It requires a large share of the vehicle fleet to be electric, which is far from the case in Sweden, unlike in neighbouring Norway and Denmark.<\/p>\n<p>Bureaucracy and a conservative automotive sector are also slowing down large-scale adoption of the technology, even though it has been available for a long time, according to professor Lina Bertling Tjernberg.<\/p>\n<p>The next major step to accelerate its development is to equip every electric vehicle with a bidirectional charging system, said Bertling Tjernberg, who is professor of power grid technologies at the Royal Institute of Technology in Stockholm.<\/p>\n<p>She lamented that incentives to promote the technology were always changing.<\/p>\n<p>Potential wear on the vehicles batteries is also a concern for some.\u00a0<\/p>\n<p>Bertling Tjernberg said this aspect needed more research although experience suggested batteries were lasting longer than expected.<\/p>\n<p>Etherden, for his part, is convinced this isn\u2019t an issue, given the evidence garnered from the past 10-20 years of using electric vehicles.<\/p>\n<p>\u201cThe battery will last longer than the car,\u201d he said, adding that powering an average home used the same amount of energy as accelerating from zero to five kilometres (zero to three miles) per hour.\u00a0\u00a0<\/p>\n<p>\u201cIt\u2019s like driving behind a donkey. It\u2019s a very careful use of the battery,\u201d he said with a smile.<\/p>\n<\/div>\n<p><!-- \u603b\u5bb9\u5668\uff1a\u6700\u5927\u5bbd908px Grid\u7d27\u51d1\u5e03\u5c40 -->\r\n<div style=\"display: grid;
