Bitcoin is expected to consume enough energy to power Austria by the end of 2018

Though bitcoin ‘s value may rise and fall dramatically, the energy required to produce bitcoins seems to be ever on the rise. Researchers estimate that the bitcoin network may consume as much as 7.7 gigawatts of energy , the equivalent of the electricity required to power Austria. If the value of bitcoin continues to rise, the entire bitcoin network may one day consume up to five percent of the world’s energy. A new study published in the journal   Joule  predicts that bitcoins use up to half a percent of the world’s total energy supply. Critics question the study’s assumptions and claim a lack of sufficient evidence to determine future bitcoin energy consumption with such precision. Regardless, bitcoin’s rising price could come with significant environmental costs. The bitcoin network primarily consumes energy through “mining” of the cryptocurrency, which occurs by running a computer program and time-stamping bitcoin transactions. These transactions take place on the blockchain, the networked account system behind cryptocurrencies. “The main problem is that the energy consumption primarily relates to how agreement on the underlying blockchain is reached,” blockchain specialist and study author Alex de Vries  told Gizmodo . “Mining makes it a big competitive lottery where the winner — every 10 minutes — gets to create the next block for the blockchain. The built-in reward for this process is fixed, so it motivates participants to constantly add new machines to the network to get a bigger slice of the pie — the more computational power, the more you win.” Related: Bitcoin mining powers Canadian man’s innovative aquaponic garden In his study, de Vries focused on determining the cost of maintaining the network after bitcoin mining becomes unprofitable. “In essence I’m taking an economic point of view to figure out where energy consumption is heading. Previous work typically looked at available hardware, and produced results that only said something about the current consumption,” de Vries said. “My findings were based on the current conditions, so bitcoin doesn’t need to increase in value for the conclusion to hold.” Some experts disagree with de Vries’ methods and conclusions. “A major limitation of de Vries’ model is that it depends on guessing bitcoin’s future price as well as the cost of electricity to miners,” bitcoin investor  Marc Bevand told Gizmodo . “In the paper he assumes bitcoin maintains its current level at approximately $8,000 and electricity costs $0.05 per kWh. If either bitcoin goes up or electricity costs plummet, the energy consumption should increase, and vice versa.” Though the endeavor to determine the future of bitcoin and other cryptocurrencies continues, it seems clear that the environmental impact of bitcoin may be steep.

Earth’s population just hit 7.5 billion people

Comments Off on Earth’s population just hit 7.5 billion people

Over 7.5 billion people now reside on planet Earth , according to the World Population Clock . But with more people could comes less access to resources like food and energy . A global population of 7.5 billion people has far-reaching repercussions – including increased greenhouse gas emissions , strained food supplies, and increased total consumption, according to Charity organization Population Matters . Population Matters says that population growth could keep some countries in poverty , and it intrudes on land needed by wildlife . Head of Campaigns Alistair Currie told edie.net , “We will see cutthroat competition for shrinking resources which will include not just fossil fuels but productive land and water, pushing prices up not just for consumers but for the businesses and industries which need them too. Huge potential markets like much of sub-Saharan Africa will be stuck in poverty and we’ll see political instability arising from population and migration pressures, including conflict over resources.” China has the most people in one country; 1.38 billion people live there. India is next with 1.34 billion, followed by the United States with 326 million. The United Nations thinks our global population will hit 10 billion people by the year 2056. Related: Scientists say the world is “one crop breeding cycle away from starvation” Currie warned that while businesses may see increased global population as the opportunity to gain more customers, too much growth won’t be good for our planet – or business. He said, “Growth cannot continue indefinitely on a finite planet and fewer consumers is ultimately better for all of us. Business must start recognizing and adapting to that reality. With action now, we can limit population growth and eventually reach sustainable levels.” We’re currently using up the resources of 1.6 Earths , and we’ll need 3 Earths by 2050 unless we can alter our consumption patterns. + Population Matters Via edie Images via Stròlic Furlàn – Davide Gabino on Flickr and McKay Savage on Flickr

Although avoidable household food waste has been cut by 21 percent to 4.2m tons since 2007, saving consumers almost £13bn a year, up to 24 meals a month and 4.2 million tons of wasted food and drink that could have been consumed goes to landfills instead.
