Electric autos tricks and renewable energy technology from Daniel Sumanth, TX: The undeniably high-end Model S has been out for several years now, though. The longest-range models had a six-figure new price, but unlike contemporary Bentley, Jaguar and BMW saloons they have held their value well. Too well, in fact; last year they started from £25,000 secondhand, now, the cheapest are usually nearer £34,000. Tesla slashed the new price of certain models by up to £30,000 in early 2019, knocking residuals for a time but now the Model S represents terrible value for a secondhand car. Buy a nearly-new one, or wait for prices to settle. Tesla’s tendency to sell upgrades and offer over-the-air updates means that a 2015 Model S may be a very different car by 2022, but with no major changes to the design, and continued reliance on the Supercharger network for efficient charging, the experience of a used Tesla won’t be much different to the rarefied heights of a showroom-fresh example. Just don’t expect to get a full charge overnight from your household socket… Read additional details on Daniel Sumanth Texas

If your average daily mileage exceeds the range of your electric car, we’d advise you to think twice, but the occasional longer trip should be perfectly manageable. As the technology improves and the average range of electric cars grows, more and more people will find that they could live quite happily with an electric car. The list prices of electric cars can look expensive compared to equivalent petrol or diesel models, even when the Government’s plug-in car grant has been applied, but looks are very likely to be deceiving. List prices are just one part of the cost of vehicle ownership and the overall cost becomes much more palatable when you factor-in the relatively low running costs of EVs – often around 60% of those of a similar petrol model depending on usage patterns. As a general rule, charging an electric car is far cheaper than fueling a petrol or diesel one – even if you use more expensive public charging points.

Although pollution related to solar energy systems is far less compared to other sources of energy, solar energy can be associated with pollution. Transportation and installation of solar systems have been associated with the emission of greenhouse gases. There are also some toxic materials and hazardous products used during the manufacturing process of solar photovoltaics, which can indirectly affect the environment. Nevertheless, solar energy pollutes far less than other alternative energy sources.

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.

Solar energy has to be used right away, or it can be stored in large batteries. These batteries, used in off-the-grid solar systems, can be charged during the day so that the energy is used at night. This is a good solution for using solar energy all day long but it is also quite expensive. In most cases, it is smarter to just use solar energy during the day and take energy from the grid during the night (you can only do this if your system is connected to the grid). Luckily your energy demand is usually higher during the day so you can meet most of it with solar energy.

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).

There’s no lack of choice when it comes to the electric SUVs on the Texas market in 2022. From the affordable MG ZS EV – winner of our 2022 Car of the Year and Best Value Electric Car awards – to the exciting Ford Mustang Mach-E and Tesla Model Y, these zero-emissions family haulers boast a desirable set of attributes: fashionable styling, useful practicality and low running costs. In addition, company-car drivers will enjoy electric SUVs’ rock-bottom Benefit-in-Kind (BiK) rates, while those who frequently drive into central London will appreciate their exemption from the Congestion Charge (until 2025, at least). The number of electric SUVs on the market is constantly expanding. Polestar, Smart, Toyota, Subaru and Lotus are all launching new ones during 2022, while Kia’s upcoming flagship will be a zero-emissions seven-seater and a pure-electric Range Rover is set to arrive by 2024.

How many solar panels are needed to run a house? So, a 2,000 square foot home would be allowed a solar array of 4,000 watts. Depending on the type of panel that you choose, a system of this size would be anywhere from 12-18 solar panels. Keep in mind, this formula to estimate consumption varies depending on who provides your electricity.
