Rising energy costs? Go renewable!

Global energy costs are skyrocketing in countries across the world. In most countries the cost of electricity supplied by the grid has increased twofold or more! This is of course not great for consumers who ideally want the lowest price possible. So why is this happening? and what can you do to bring down the electricity costs for your home, school or business? First we will address the former question: Why is this happening? As with a lot of things, it comes down to a case of economics. Supply of electricity across the world has decreased, with electricity providers struggling to efficiently run power plants. A cold winter across Europe has meant that more supplies have been used up when heating homes, leading to a reduced supply of natural gas, an important fuel in today’s economy. Couple this with lower natural gas export quantities for large providers of the substance such as Russia to Europe under political tensions and you can see how prices are increasing!


Energy misbalance


Global demand for electricity is not only staying level, it is growing, quite rapidly. Particularly with a hot summer across Asia, increasing the use of air conditioning across the continent, a very energy hungry process. As supply is decreasing and demand is increasing there is a misbalance between consumers and producers. Hence the cost of electricity rises in response. As the demand outstrips supply by a high degree it is possible for the prices to increase so much. In some cases such as Denmark this can reach energy prices of up to 200%+ of the electricity prices in 2022!


You may think: what is my government doing about this? And that would be an excellent question! Many governments apply an energy price cap on household electricity bills to ensure the less well off are protected from fluctuations in the energy market and rising energy prices. Effectively this means the price of electricity for the consumer cannot exceed a certain amount with the government covering the difference in power. An example of a system like this is in place in Great Britain. The system involves ensuring the cost of electricity does not affect consumers too much. Unfortunately again for consumers in the UK, this price cap is increasing by 54% come April, leading to higher living costs for the region.

Becoming independent energy user


So the second question and, I should think, the more important one. How can you bring down electricity prices for your home? What are some of the most effective ways to avoid this price hike in electricity prices? What can you do?! Having at home power generation helps to disconnect your house and electricity bills from fluctuations in the overall energy markets. By having a personal power generation system you can generate the electricity you need without having to rely on natural gas supplies on the other side of the world!


Obviously it is going to be a little tricky to build a functioning natural gas power plant in your back garden, and that would do nothing for rising gas prices! Of course renewable energy is the way to go when constructing small scale power generation systems. The compact nature of renewable energy devices and their scalability down to this size makes them an excellent choice for power generation that can fit in your garden, on your roof or outside your driveway!

There are a few good choices of power sources your devices could draw from. Renewable energy comes in many different forms: tidal, solar, wind, hydroelectric and more! Unfortunately most people do not have access to an ocean in their back garden. As a result the most usable technologies for most people rely on solar and wind energy, this is because the technology behind the electricity generation has developed to the point of which you can mount it to your roof. As well as the almost universal access to these two sources of natural power, given that the sun shines and the wind blows all over the earth.


What TESUP does?

TESUP is, of course, a manufacturer, supplier and designer of domestic wind turbines so this is where the main expertise of TESUP lies. TESUP has a great range of domestic wind turbines to choose from to fit into many applications as well as flexible solar panels to use in those tricky not so windy spots! Installing a domestic sized wind turbine on your roof is a great way to start generating your own electricity for your house, avoiding the high gas driven prices and reducing your impact on the environment.

Energy cost calculations

It’s all well and good saying the turbines can help you generate electricity with these new electricity prices but it would be helpful to have some numbers, right? Don’t worry TESUP has you covered! We will take the example of a 5kW Magnum 5 turbine, one of TESUP’s best selling turbines. Installing one Magnum 5 turbine would, if constantly spinning at its rated speed, generate 3600kWh per month! This would amount to $2700 in Germany when the expected average price of 2022 comes into force at $0.75/kWh


The wind is, however, quite unpredictable at times. Wind cannot be expected to be constantly blowing with enough speed to turn your wind turbine. So we need to work out a capacity factor for the wind turbine: the percentage of time the turbine is expected to spin in a way that generates power. A good estimate of this is about 25% capacity factor in a moderately windy country (most european countries) with a turbine with a low starting speed such as a Magnum 5. At this capacity factor an estimated 900kWh is generated (when spinning at rated wind speeds). Amounting to a tidy sum of $675 per month!



So you can see, a good way to avoid, and even potentially benefit from rising energy prices is to develop your very own energy generation system. And why stop at one turbine, if you already have the other aspects such as charge control in place, it is easy to integrate more turbines and generate even more energy and potentially end up with a profit!
