Breakthrough In The Cost Of Solar And Wind Energy

solar and wind energy

One of the fastest and the most amazing turns in the history of energy occurred: in many areas the construction and operation of the new renewable energy became now cheaper than simply operating the existing coal and nuclear power plants. Actually, it is quite possible to survive without coal power – the recent experience of the Uk has proved that fact.

There is a conclusion from the whole-used yearly benchmarking study – the Levelized Cost of Energy Analysis (LCOE) from the financial firm Lazard Ltd.: the operating price of generation technologies (coal or nuclear) bear more costs than the full life-cycle costs of construction and operation projects that are based on the use of renewable energy sources.

Lazard is one of the leading financial consulting companies, as well as asset management companies in the world for many years. It was interested in the cost of energy from the plant in North America. It also focused on the following: how the growing economic advantage of renewable energy in the US “will contribute to an even deeper penetration of the sun and wind here”.

Expanding the Boundaries

But Lazard also wonders if it is more expensive to exploit conventional energy sources in the developing world than in the United States. Thus, in India and China, the number of electricity markets is growing rapidly and because of it the advantage of renewable energy sources compared to traditional sources is even larger there.

Let’s understand why the cost of new renewable energy sources for the whole lifetime is much cheaper than the new coal and nuclear energy. This happens because the capacity of new renewable energy sources is cheaper than electricity from existing coal and nuclear fuel. And this gap continues to grow.

In North America, the cost of solar energy and wind power fell by 6 percent last year,” – Lazard emphasizes. This was due to the fact that the price of coal remained at the same level and the cost of nuclear increased. The analysis suggests the following: compared with previous estimates estimated settlement cost of energy for nuclear generation increased by 35% and this reflects an increase in capital expenditures for the various nuclear facilities, which are under development.

In this remarkable diagram, which Lazard demonstrated to us, nuclear energy simply rated itself out of the market for a new power. But at that time, solar and wind energy fell sharply in price since 2009 and solar power is becoming less expensive than natural gas!

The Cost Issue

Comparing the cost of the life cycle of electricity in new nuclear power plants and solar power and wind, we arrive at powered by solarthe following data: the first value is now in the US $ 148. per megawatt-hour or 14.8 cents per kilowatt-hour, whereas 5 to / kWh for solar energy, and 4.5 c / kWh for wind. To compare, in the US there is the average price for electricity 11 cents per kWh.

Therefore, there is no great shock that in the United States only one new nuclear power plant is still under construction. It is also not surprising that even existing power plants are struggling to remain competitive.

The Bloomberg New Energy Finance report, which was published this summer, made the following conclusions: more than half of all existing US nuclear power plants are “bleeding money”. For Secretary Rick Perry was made a draft report from the staff of the US Department of Energy, which agreed that coal and nuclear resources are not economic anymore.

According to the diagram, new gas plants are more expensive than new solar panels and wind. The fact that solar energy and wind are changing still gives new opportunities for gas in some markets.  Since the price of electricity storage, including lithium-ion batteries, fell abruptly the future of renewable energy is more promising than before.

Homemade Solar Hot Dog Cooker for Your Kid’s School Project

solar hot dog cooker

Just think: one day your kid comes home from school and asks you to help with his upcoming school project. The years of school and physics are far behind, so does your science knowledge, so you have no idea what kind of project it can possibly be.

How to impress your kid’s teachers and school pals, get a good grade and at the same teach your kid something useful? Solar Panels Company blog offers you an idea – consider of making a hot dog cooker run on solar energy. Even if you are not an expert in science, you will most likely get it done since this solar hot dog cooker requires minimal efforts and materials to build.

Aside from it, you will have a chance to teach your kids more about the alternative energy that can help the environment and save a bunch of money. So here is how you can make an eco-friendly hot dog cooking appliance.


  • Long box
  • Utility knife
  • Aluminum tin foil and poster board or a thin plastic mirror
  • 2 wooden dowels
  • Drill
  • Skewer
  • Ruler (to produce the formula for a parabola)
  • Tape
  • Scissors or utility knife
  • Glue
  • Hot dogs


  1. Find the longest box with an open top in your house. The larger it is, the more hot dogs you’ll be able to cook at one time.
  2. Cut the side parts of your box in a shape of a parabola (half of the oval). Speaking of the parabola formula, let your child figure out the formula and come up with the point of focus on his own. The actual formula for a parabola is Y = X2/(4F), where X is the horizontal distance from the origin, F is the focal distance and Y is the vertical distance to the curve at any point X.
  3. Cut the poster paper to cover the top of the box with the parabola. Cover the poster board with foil and attach it to the box. Instead of a tin foil, you can use a thin plastic mirror.

So, how does it all work? On a sunny day, the construction should be faced directly at the sun (don’t forget to adjust the cooker as the sun changes its position). To fix the incident sun rays at a certain point where the heating occurs (in our case, this is a hot dog), you need to have the parable-shaped mirror. String 1 or 2 hot dogs on a skewer and wait approximately 6-12 minutes to cook the hot dogs.

By the way, here is another way to use solar energy and complete a school task – homemade solar cells!

The most important part of it is patience. First, it seems like nothing happens to hot dogs, but if you do everything right, the process will go. Don’t forget to rotate the skewer every now and then. As soon as hot dogs are ready, enjoy!

Cooking with a little bit of science is fun, how do you think?

Is Solar-Powered Bitcoin Mining the Future?

bitcoin and solar power

In 2017 Bitcoin proved to be worth investing in it. Nowadays more and more people want to mine it. But the problem is that Bitcoin mining consumes a big amount of electricity by special software that look for the right hash keys to mine Bitcoin. Some miners from Iceland have launched a business of using the geothermal power, but most of the world is trying to cut down the electricity expenses.

The Idea Is Not New

Yet, the most discussible way of running the operation of Bitcoin mining is the solar power. Bitcoin and this energy source have a quite long relationship. In 2012 one forum conversation on wrote up the setup of mining operation based on the solar energy in Australia. Back then Bitcoin was not on the wave of popularity and some in the financial world had become disillusioned with cryptocurrency. But mining-powered by solar energy was anyway being discussed on the internet.

For instance, in 2013 a cryptocurrency fan published a guide on building the mining plant, powered by the energy of the sun. In 2015, one more Bitcoin fan downloaded a video on Youtube to boast of his solar power mining farm. They reported that the power their S3 Antminer consumes was fully compensated by the power of solar energy through the solar panels.

Bitcoin started attracting a lot of attention in the middle of 2017. This year the user of Reddit informed about their solar mining operation in the Southwest desert. They unraveled, that their every miner was creating .007 Bitcoin every day by virtue of the solar power. This team was also searching for the ways to increase the mining rigs number because the process developed so successfully.

The user made an observation, that Antminer S9 ASICS mining system was worth near $1,225 at the present writing. Each mining operation cost $8,000 together with 6kW solar panels, deep cycle lead-acid batteries, and a power control system.

The sum of $8,000 may seem to be high. But some people think that the power of sun really could make mining more competitive. Nowadays the majority of mining operations is provided by huge companies with incredibly powerful machines. The small mining firms or individuals are in the past. That is why some cryptocurrencies of the future become resistant to ASIC.

The Electricity Issue

Bitcoin mining is mostly centered around (or blocked) by the prices of electricity. Thus, the solar power has the huge potential to turn mining into an easier and more accessible process, especially given the fact that solar power is gaining more popularity.

There is a presumption, that mining companies could use the renewable energy tax credits. It can happen if they take advantage of solar panels in order to power their operations. This probably could offset some part of taxation load connected with Bitcoin selling.

Tam Hunt of Greentechmedia counted in September that one 1-megawatt project of Bitcoin mining could be worth no fewer than $9.3 million dollars. In addition, a 20-year net revenue of near $19 million. These calculations were made on the basis of a Bitcoin price of $2,500. The price of Bitcoin has considerably increased since then. These calculations are looking quite good in comparison to the common 1-megawatt solar project. It is worth on average $200,000 to $400,000.

The Benefits

Bitcoin miners, that power their firms with the solar energy, make extra money when connecting solar panels to a power grid. solar panels on the roofIt helps them to sell excessive energy to the utility company.  This method can come into play if one grows cold to Bitcoin or if the Bitcoin value goes down or even collapses. Actually, many people already managed to save money by installing solar panels on the roof.

Prospective miners could benefit from the lack of mining approval requirements in states like Texas. They could install solar panels and equipment for mining as soon as they buy a land there. Rural areas are the best place for solar panels.  They occupy a large territory and the prices on the land are low there as well.

The solar energy gets more and more famous across the populations and nations. So there is no wonder that bitcoin miners want to take advantage of it as well. It is pretty simple to buy and install the solar panels.  They are constantly improving with the change of technology. Solar panels make the miner’s operations flexible, while they can install them wherever they want, even on the transparent surfaces.

In course of time, the algorithm of Bitcoin mining gets more and more complicated. One researcher assumed in 2016, that a continuous electricity consumption of Bitcoin plants can reach the total output of a little nation like Denmark by 2020.

Transparent Solar Technology as a New ‘Wave of the Future’

solar energy sourceThis year is told to be a new era of the solar technologies. That is because of a new invention called ‘transparent solar panels’. The experts from the Michigan State University are saying that the new way of getting the electricity is going to bring a completely new system of getting the electricity. Everything from our cars and phones to the windows is going to change. Everything that has a transparent part will transform to not just serve its old features, but also to produce the electricity to people.

A bold statement has been said by the inventors that the new technologies would be able to ‘almost cover the U.S power needs’. One of the experts in an interview says that we are just beginning to hit this new era, and soon we are going to meet a new amount of marketing of this new technology.

Mr. Lunt from MSU and his colleagues are the pioneers of this field. Last year they found out about these new materials that have not been used in the solar panels yet. Those materials pick up the ultraviolet light to produce energy from it. This allows the manufacturers to install it in all of the transparent surfaces, including all types of windows, meaning that by being installed in all of the house’s windows this will allow shortening the amount of money spent on the other types of electricity. Moreover, unlike the old system of the usual solar panels, this will allow to still keep the transparency completely the same as it was before. The material will not blur the picture, nor do any kind of a harm to anything around it.

By the way, have you heard that recently Britain spent the whole day without coal energy? That was a great step for the country’s ecology.

transparent solar panelsHowever, there are still a lot of things to work on for the MSU experts. This new technology still does not fit the needs of bigger houses or shaded places. In addition, the problem with it is that a moving surface will still get less sunlight, therefore making this system less useful for the cars. Moreover, it is said that the efficiency of the transparent solar panels is less than its older brothers. The inventors claim that a clear panel will have up to a 5% efficiency on a totally sunny day, while the normal panels will bring you from 10% to 15%, depending on the type.

Anyways, this new invention seems to be one of the biggest breakdowns in the power development systems in the past decades. Looking at the things with the optimism, we are going to see that if the research has enough foundation it will be developed to be one of the most important systems in the electricity sphere. Just in the United States, a huge amount of glass surfaces might be used to serve the needs of the people. The researchers say that those 5-7 billions square meters will be able to cover almost a half of the energy consumption in the country. Moreover, with the development of the new systems, this number will rise to almost a hundred, being a new era technology from the future.

In the end, it is important to say that even being a potentially a new breakdown in the power supplement field, the transparent solar panels are too expensive to be used right now. It is also not rentable to use it in most of the cases since by installing a solar panel on the roof of the building would bring much more power for a lower price. However, if the technology advances to at least the same level as the normal solar panels this will be a new chapter in the electricity.

The Country That Survived A Whole Day Without Coal Energy

cola energy producersSince the industrial revolution, the main source of power in Britain was the coal energy. However, this year, 135 years after the start of the first coal power plant, the situation had changed.

On the 21st of April, 2017 the United Kingdom powered a whole day without the coal energy at all. For the first time in this period of time, no coal energy was used. The biggest part of the energy consumed that day was by the natural gas power stations; quarter by the nuclear power plants, the number of which is decreasing every year too. And the other part was the so-called alternative sources such as the wind power and the biomass.

 A Positive Step for the British Ecology

That was only the collision of the factors that allowed this achievement to happen. Yet, this shows the great work that the British Government is doing to decrease the percentage of coal energy in the UK general energy production. The official data show that in 2016 the amount of energy generated by wind was higher than the amount of energy generated by coal.

It is also a sign that the alternative energy sources are getting more and more attention, which might lead to the decreasing of the prices for the wind and solar stations. It also implies that, since the power plants are closing, the UK’s diversion of the energy sources is getting bigger and bigger with every year, which is good for both environment and the economy. Perhaps, the UK will be the country that will make use of these solar inventions?

Environmental Organizations Reaction

protection against the pollution

The biggest environmental organizations have already commented the event as the milestone to the independence from the coal energy. This is also considered to be a new step towards the growth of the alternative types of energy, which is a great sign for the ecology. It is a well-known fact that the coal power plants were the biggest pollution makers out of all types of the power plants and now there is a chance that solar energy will dominate as an alternative energy source in the nearest future.

The Vector of Development

The United Kingdom WWF scientist said that it is important for the next UK Government to keep up the pace, and work on this problem even more because the future is behind the alternative types of energy, that are not causing the environmental problems like the coal energy.

Mr. Redmond-King also mentions that the new politicians have to work on the problem like decarbonizing the buildings and transport – a trend that was set by the European scientists and has been approved all around the European Union. According to the scientists, Britain is far behind the other countries of EU since they have not yet done anything to fix this problem.

This Is Not the End

However, it is important to remember that this 24-hour event was just a collision of the factors that helped the UK ‘survive’ without the coal energy. Therefore, it is important to remember that for now, it would be hard for Britain to hold on without the coal. Which means that the alternative sources of energy have to be given a bigger budget and that the priority should be given to those in the future.

More news about alternative energy sources: Tesla Motors is making steps towards becoming the first foreign car company in China.

Tesla is About to Build its First Manufacturing Plant in China

Tesla car, China, solar panelsTesla Motors makes steps towards becoming the first foreign car company in China with a manufacturing plant in the Shanghai’s free-trade zone. As the provider of solar panel companies reviews states, the company didn’t want to follow all global carmakers and set up a joint venture with a Chinese partner. They went an alternative way and negotiated a deal with the Shanghai’s government requiring the company to build their own factory in China.

As reported by the two people familiar with the negotiations, a preliminary agreement between Tesla and the city’s local authorities, the company received its property rights on the plant. The Tesla EV production is going to be operated inside a free-trade zone, which means the company has to impose steep tariffs on its products as though they were shipped from other the country. The two persons preferred to stay anonymous because they were not at liberty to reveal the details of this deal.

In spite of these preliminary agreement conditions, there is a chance that future negotiations with the Chinese government can end up with even better terms for the company. The plan is to make a new agreement by the end of 2017.

By the way, China and India were reported to contribute the most to the increase of the PV technology in 2017

Both ways, the profit remains equal for both sides: Tesla Motors gets the world’s largest market for electric cars while China becomes several steps closer to dominating the global electric car industry. The fact that Tesla will manufacture its EVs in the areas of Shanghai will be the second impetus for consumers all across China to purchase electrical cars instead of regular vehicles powered by gasoline. The first reason is the country’s extensive subsidies for electric vehicles that help China not only fight the air pollution issues but also reduce the amount of imported oil.

These are predictions from LMC Automotive, a global consulting firm, suggesting that more than 295,000 battery-electric cars are about to be sold in China by 2017, which is 8 thousand more from the total amount (287,000) of cars sold in the rest of the world.

Currently, China has strict rules regarding the auto trade with all the largest car companies requiring to pay huge steep tariffs (25 percent) on imported vehicles. In comparison, the European Union charges 9.8% and the U.S. tariff only 2.9%. Due to such unbelievably high tariffs on imported cars, foreign manufacturers find their products tough to compete with the ones produced directly in China. The country is interested in growing their own auto industry and making it more competitive.

As a matter of fact, the high price for automobiles isn’t caused by high shipping costs (this one makes up only 1-3 percent of the total cost of a car). The price depends directly on whether there is a 25% tariff or not.

The US president Donald Trump already plans to visit Beijing on the 8-10 November, however, there is a little chance China and the US can come to some important negotiations in the EV industry. If Tesla is allowed to operate its plant outside a free-trade zone, it will be a real breakthrough for a foreign car manufacturer since the times such a permission became available for Honda.
