bitcoin energy challenges

Bitcoin and Rising Ecological Concerns

The virtual currency broke new records last night, exceeding $14,000 on 7 December, before retreating. But the way in which bitcoin is created is not without consequences, especially regarding the environment.

Cryptocurrency craze around the world

Bitcoin is a cryptographic currency, (digital money), without real coins, banknotes or central bank notes. It is based on the blockchain, which is a kind of dematerialized, tamper-proof general ledger of accounts shared between millions of peer-to-peer computers.

For some, bitcoin is not a real currency. Nevertheless, it can be used for shopping, mainly on the Internet, but also in some physical stores. Since the beginning of the year, the price of bitcoin has increased tenfold. And it’s not over yet. People’s main criticism relates to the fact that cryptocurrencies like Bitcoin can be purchased in an anonymous way as explained on this “achat de bitcoins sans verification d’identité” guide.

Like gold diggers

a mining rigHow does the bitcoin work? To secure transactions, we need to solve mathematical equations, very complex problems, by the use of powerful computers. Anyone can use a computer to do this job. Miners (people dedicating hash power to secure the network) are then rewarded in Bitcoins.

Because this helps to create new bitcoins, this activity is very similar to that of gold diggers or miners digging for ore and is increasing every day.

Even if all this activity is virtual, there is a finite amount of bitcoins: 21 million, exactly. The mining of Bitcoins, as well as other cryptocurrencies (more than 1300 as of today), can bring in a few hundred euros per month. It all depends on how much computing power you are willing to dedicate to it.

Over-consumption of electricity

More and more people around the world are starting to mine bitcoins and other “Alt” coins. There are even mining farms, giant warehouses stuffed with computers and mining rigs, which are only used for this purpose. Most of them are found in Iceland or China as energy is quite cheap there.

A lot of people have also been caught doing crypto-jacking lately, which is pirate mining via contaminated computers used without the knowledge of their owners. As a result, all this increases electricity consumption.

According to a specialist analyst, bitcoin accounts for 0.14% of global electricity consumption. Every new transaction in this currency would consume as much electricity as a French household over the period of two weeks. And there are about 300,000 transactions a day. Some people are beginning to talk about an “ecological disaster.”

There are still a few hopefuls with new mining algorithms that are less energy-intensive and new computer chips that are less energy-intensive. Miners are also starting to invest massively into solar energy which should help in reducing the energy impact on the planet.

Bitcoin and other digital currencies are still new with less than ten years of activity for the mother of all coins, but it would not be fair to judge such a relatively new technology without giving it some time to sort out its main challenges.

Australia: The world’s most powerful battery powered by Tesla

Some 30,000 households in southern Australia can now say goodbye to frequent power outages thanks to Tesla’s activation of the world’s most powerful battery.

Located in Jamestown, about 200 km north of Adelaide in the state of South Australia, the giant lithium-ion battery has a capacity of 100 megawatts, about 1/16 that of the Manic-5 powerhouse in Quebec.

According to CNN, it is three times more powerful than the previous record holder.

The battery, which will start working on Thursday, is used to store the energy produced by an adjacent wind power plant. When the demand for electricity increases or production decreases, the battery goes into action to power up to 30,000 homes in the surrounding area for an hour.

South Australia, a large part of which is deserted, suffers from frequent power outages that complicate the lives of its inhabitants.

Elon Musk, Tesla’s CEO, had bet on Twitter that his company would be able to build the stack in 100 days or less, failing which he would pay the bill himself. In the end, the Australian taxpayers will have to bear the costs, since the bet was raised in only 60 days.

Tesla installed Similar, but less powerful batteries in California, Hawaii, New Zealand, the United Kingdom and several Pacific islands.

Tesla also mentioned the idea of installing them in Puerto Rico, whose electricity grid was severely damaged by Hurricane Maria in September.

3 Benefits of Green Electrical Sources of Energy in Africa

Do you want to know the benefits of green electrical sources of energy in Africa? Green energy has lots of benefits to the environment and economies of African nations. For instance, it reduces pollution and global greenhouse emissions, which results in us enjoying a better environment.

ttyuiopllkkkvvvvvvvvAnother reason that should make you consider using green energy sources is that they are renewable. That’s because they are replenished relatively quickly and naturally. This post looks at three benefits of green energy to African nations.

Creates Job Opportunities

The growing development of green electrical energy in Africa means that more jobs are getting created. For instance, the INTERNATIONAL RENEWABLE ENERGY AGENCY (IRENA), in a study, found that green energy production created 7.7 million jobs in the year 2014 around the world. This agency predicts that 16 million jobs will be set up by the year 2030 if this trend goes on.

Less Service Disruption

It means that if one geographical area experiences disruptions, other areas or equipment won’t be affected, meaning that places such as hospitals in Africa find the green energy to be reliable.

Going Green Leads to a Stronger Economy

Green energy sources have an additional advantage to the economy. The reason is that governments in Africa collect taxes from renewable energy projects, which are then used to provide public services. The jobs resulting from these projects lead to the creation of jobs in related industries, which means that homes and businesses benefit.


Green electrical sources of energy, such as water, wind and solar have many benefits to African nations. It means that companies that deal with renewable energy should consider the African market since it is one area that hasn’t been explored much.…

Steam cleaning helps local communities in Africa

The effects of steam cleaning versus normal cleaning

Regardless of the method used, the result will define the effectiveness of the tools that have been chosen. The ends justify the means, with the constraints of the daily life, especially in countries where access to water is not granted…

During working days, we have little time to devote to the things we love and beings with our loved ones. On weekends, we only dream of enjoying these two days offs offered, but there are still the heavy burdens of household chores. Over the last few decades, we have seen the birth of several powerful tools to facilitate our daily lives.

Currently, we have several devices that do at least half the work in our place. Indeed, for the cleaning of the interior, we have only the embarrassment of choice about the tools to be used. Between normal cleaning with a normal vacuum cleaner and steam cleaning, what is the difference? Through our Guide D Achat Nettoyeur Vapeur we invite you to discover more through the next few paragraphs.

How does a normal vacuum cleaner work?

vaccum cleaners are handyA vacuum cleaner, as the name suggests works by sucking up dust, fibers, crumbs as well as all the other dirt that gets into the house. Refer to the operation of the fan and note that the vacuum cleaner operates in reverse order. It sucks dirt with its engine which emits a depressurization in the dust container.

First of all, it uses filters that are the first to suck up dirt. The biggest ones stop at the first level and the others continue on their way to the filter. These two suction systems lead to a receptacle that collects all the polluting elements. It is then enough to empty the receptacle and to start over the cleaning if necessary.

How does a steam cleaner work?

With the same features as a regular vacuum cleaner, the steam cleaner also absorbs the pollutants and allergens that are present in the room. For this second type of device, the dirt is sucked in by moist air. A damp cloth takes the place of the filters. This cloth receives the steam emitted by a boiler containing heated or boiling water. To do this, simply connect the appliance to a power source to heat the boiler. Then, as the temperature of the water increases, the cloth gets wet with steam. So you’ll feel like wiping the surface of your home with a damp cloth.

The operation of this device is carried out in a few steps. First, the steam is released through the wipes at the brushes. Then, the vacuum cleaner starts to absorb the dirt in the room with a filter. This filter is connected to a receptacle, generally transparent, which receives the dirty water. After that, the treated surface remains slightly moist and easily dried in air.

The benefits of normal cleaning

With a conventional vacuum cleaner, you act as if you are spending a broom in your home. Simply walk the appliance on the places to be cleaned, and the vacuum cleaner itself absorbs the polluting and allergenic elements that are in the room. When you do the cleaning, you only need your device.

There is no need to wait for any heating time or a long enough time for the cooling of the appliance. The only limit of the device is the capacity of its recovery tank. When it is full, you must empty it and then reinstall it before cleaning or storing the unit again.

The benefits of a steam cleaner

The first advantage of a steam cleaner is that it can be used on all surfaces of the house, from floor to ceiling, tile windows and even garage. For best results, this unit is equipped with extension tubes which help us to reach the most distant places like the ceiling or the tops of the furniture. On tiles and windows, it is no longer necessary to use detergents to make them glossy and shiny. We also do not need to spray water on tiled and glazed surfaces, as the appliance is already operating at humidity. Find a  here for more here

Why Preserve Energy at Your Home

Energy saving is not just an environment-friendly behaviour, but it also helps you save on the utility bills. Preserving energy is getting important as the non-renewable resources of energy are replaced by renewable sources of energy. Renewable energy resources include solar energy, tidal power, hydropower, wind power, etc. that are replacing nuclear power like coal, oil or fossil at your home to preserve energy. These non-renewable resources of energy come from burning decaying plants or fossil fuels thus they emit harmful gases like carbon dioxide that harm the environment.

The consumption of energy proves to be adding to harmful effects to the environment like global warming. The more energy we consume, the more we provide the earth’s environment to add to the occurrence of acid rain thus more air and water pollution. With preserving energy, you avoid adding to ozone layer depletion, climate change and also reduce the emission of carbon dioxide into the air.

All of the non-renewable energy resources are unlimited in the supply of nature, and so it means they come from nature and thus also do not provide any harm to nature. On the other hand using renewable can automatically preserve the non-renewable resources. Using the energy carefully can also help you save cost. Rearrangement of the furniture on the position of the windows, doors and air condition can help you save energy. By sealing ducts and opting for the proper insulation, you can preserve the energy when the cooling or heating systems are being used.

By preserving energy, you can use it for longer compared to when you are careless about its consumption. Being careful means following some energy efficient hacks around the house. Replace the incandescent light bulbs with compact fluorescent light bulbs which save up to 75 % of the energy thus you both preserve it and save on the bill.

Protecting energy through efficient consumption means a little amount of utility bills thus more disposable income. The less you consume the energy, the less is the emission of harmful rays of energy onto the environment. The trending behaviour of energy saving is slowly changing the way people use energy in their daily lives thus in return the market provides a hand in it as well. There are energy efficient electrical appliances with environment-friendly solar powered heating or cooling system.…

2017 Project: Building Classrooms in Madagascar

Lovy, aged 4, will begin attending preschool this year. He is one of the 200 pre-school children in rural Belalanda, 10 km from Tulear. Lovy will be among the beneficiaries of the construction of a classroom for preschoolers within the Public Primary School (PPS) of his commune. Fasimera Juliette, her mother, was very pleased when she heard the news: “I am delighted to know that my son will finally be able to go to school. It’s hard to sell mangoes with a month-old baby in your arms and another child following you everywhere, “she said, obviously relieved. Abandoned by her husband three years ago, this 36-year-old woman raises her five children alone, of which Lovy is the only son.

The construction project, funded by the Dutch Committee for UNICEF, aims to facilitate the integration of pre-school children into schools in two regions: Atsimo Andrefana and Atsimo Antsinanana, which are among the five poorest regions in Madagascar. Indeed, in these two regions, only one in ten children went to pre-school before entering primary school.

Thus, within the framework of the collaboration between UNICEF and the Ministry of National Education, 32 PPS in rural communes will benefit not only from a classroom for preschools but also from a watering place as well as toilets for the entire community. Teacher training will also be provided to ensure a better quality of pre-school education.

Statistics show the importance of preschool in the child’s educational life. In the municipality of Belalanda, the repetition rate at the level of CP1, which comes immediately after preschool is 12%. This high repetition rate is the result of the absence of preschool, says the Pedagogical Director of the PPS. “Preschool is a fundamental step for the development of children’s capacities, and children from this commune have no access to pre-school “, he said with sadness.…
