Electric vehicles information and renewable energy technology with Daniel Sumanth, TX: Not everything Smart has produced is the cleverest idea, but in the grand scheme of things the electrified ForFour isn’t a bad choice at all, as long as it’s priced accordingly. This little four-seater has the tiny charm of European city cars such as the Fiat 500 or Twingo, and that shouldn’t be a surprise as it shares a body with the latter. The electric option isn’t vastly different to the two-seater EQ ForTwo, but it’s pushing a bit more weight around. Basic, and a touch crude in places, the Smart is the opposite of the BMW i3 in terms of technical investment; it’s a conventional car adapted for electricity. The compromises are fewer than you’d think apart from the big one – or rather, the small one, as the 17.6kWh battery is about the same capacity as some plug-in hybrids now. Range suffers accordingly and you’ll be lucky to get 70 miles of motorway speeds even in summer. See extra info at https://www.fastbackgroundcheck.com/people/daniel-sumanth/id/f-8859270526765424292

In some ways, owning an EV means you have to change the way you think about driving. You automatically adopt a gentler, more relaxed style that maximises your range and often means you reach your destination feeling more refreshed than you would do otherwise. Electric cars have zero exhaust emissions so they don’t cause the localised NOx and particulate emissions that have a damaging effect on air quality in urban areas. However, the overall environmental credentials of an electric car depend greatly on the source of the electricity used to charge it. As the energy mix of the National Grid moves towards renewable sources like solar, wind and tidal power and away from fossil fuels, electric cars get greener. Green NCAP has published whole life emissions estimates for various cars with small electric vehicles performing better than any ICE cars.

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage. Moreover, not only will you be saving on the electricity bill, but if you generate more electricity than you use, the surplus will be exported back to the grid and you will receive bonus payments for that amount (considering that your solar panel system is connected to the grid). Savings can further grow if you sell excess electricity at high rates during the day and then buy electricity from the grid during the evening when the rates are lower.

Although some customers might still be a little hesitant about making the switch to electric power, one key advantage is that there is a greater selection than ever before. There are small, city car-sized EVs such as the Fiat 500, while Skoda’s capable Enyaq offers SUV practicality, and models from Porsche and Tesla offer plenty of prestige and pace. Also wading into the mix is the brilliant, yet controversial Ford Mustang-badged Mach-E SUV and of course, the Hyundai Ioniq 5 took our Car of the Year award for 2021. There are other benefits to pure-electric motoring besides the environmental credentials – you’ll be exempt from London’s congestion charge zone and from paying road tax. Electric cars still remain more expensive than their combustion engined counterparts to buy, even with the government’s plug-in car grant, but running costs have been shown to be as much as 60% less for electric cars than they are for pertol and diesel ones.

The initial cost of purchasing a solar system is fairly high. Although the UK government has introduced some schemes for encouraging the adoption of renewable energy sources, for example, the Feed-in Tariff, you still have to cover the upfront costs. This includes paying for solar panels, inverter, batteries, wiring, and for the installation. Nevertheless, solar technologies are constantly developing, so it is safe to assume that prices will go down in the future.

I mention price and quality here because generally, the old adage is true. You do get what you pay for. Diesel generators generally cost more to purchase yet tend to last the longest. One of our diesel generators is a 1996 model, the other is 2004. And our neighbor runs a 1956 (!) Lister still running strong. Gasoline models will wear out the fastest of the three types of generators although they are far cheaper on their initial purchase. Propane generators run somewhat cleaner and generally quieter than diesel or gasoline. And generators with a low rpm (typically 1800 rpm) should last longer than those that run at a faster rpm (typically 3600 rpm).

Skoda is renowned for producing great-value and well thought-out family cars with petrol and diesel engines, but the Enyaq iV is its first effort to do the same with electric power. And it’s a very good one. Using the VW Group’s dedicated MEB electric-car architecture means there’s an enormous amount of interior space for both passengers and luggage, not to mention great all-round visibility through those big windows. Technology-wise, you can choose from three different powertrain options: the Enyaq iV 60, the Enyaq iV 80 and the all-wheel-drive Enyaq iV 80x. They deliver between 255 and 336 miles of driving range, with all models getting decent rapid-charging capability so you can top up quickly on a longer journey. There are also a variety of interior ‘themes’ to choose from, with sustainable materials employed to give a unique feel to the cabin.

Usually the largest single cost factor is lighting. Obsolete light bulbs only use about ten percent of the electricity to make light. 90 percent are lost as heat. They produce heat rather than light, because they are based on a glowing filament made of tungsten. Modern LEDs use almost all of the electricity to make light. You can clearly notice this from the fact that they stay cool, i.e. there is much less loss. A good LED needs about a tenth of the electricity to produce the same amount of light. And because it does not heat up so much, it lasts much longer. And: The price of LEDs has come down so much, that exchanging them for regular light bulbs pays off within one or two years. The same is true for industrial lighting systems which often use mercury vapour lamps. These, too, use up a lot of electricity and can easily be replaced by LEDs.
