While electricity is an integral part of our daily lives, some modern technologies do not require electricity to function. These technologies rely on other energy sources, such as mechanical energy, solar energy, or kinetic energy, to operate. In this article, learn how seven modern technology examples work without electricity. Solar-powered calculators One typical instance of technology that does not require electricity is solar-powered calculators. These calculators are run on solar cells, which transform sunshine into electricity. The calculator can be powered in low light thanks to the solar cells, which are typically integrated into the calculator’s display. Calculators powered by …

How do renewable energy resources benefit Bitcoin mining in rural areas? Renewable energy sources offer a more reliable power supply for Bitcoin mining operations since they are less prone to experiencing power disruptions. Additionally, using sustainable energy for Bitcoin mining can support job growth and economic expansion in rural areas. In the context of Bitcoin, gridless computing, which refers to the usage of alternative computing resources such as edge devices, can encourage the use of renewable energy resources to mine BTC in Africa. That said, gridless computing offers an alternative to the centralized electrical grid, which is often unreliable or …

A Bitcoin (BTC) mining project that taps into clean, stranded and excess hydro energy in Malawi has picked up steam. The company behind the project, Gridless, shared that there are now “1600 families connected to this remote hydro mini-grid in the mountains of southern Malawi.” 1600 families connected to this remote hydro minigrid in the mountains of southern Malawi. They have 50kW of stranded energy that we are testing out as a new Bitcoin mining site. Videos for context.

El Salvador has passed landmark legislation providing the legal framework for a Bitcoin-backed bond — known as the “Volcano Bond” — which will be used to pay down sovereign debt and fund the construction of its proposed “Bitcoin City”. The bill passed on Jan. 11 with 62 votes for and 16 against, and is set to become law after it is ratified by President Bukele. #Plenaria90✍ Con 62 votos a favor, creamos la Ley de Emisión de Activos Digitales. pic.twitter.com/g1poXwLoH3 — Asamblea Legislativa (@AsambleaSV) January 11, 2023 The National Bitcoin Office of El Salvador announced the passage of the bill …

Climate change has become one of the most pressing issues in the modern world with mounting pressure on companies to develop and implement climate strategies. Politicians around the globe have also been actively involved, with several nations pledging to go carbon-neutral in the next couple of decades. Amid all the initiatives and conferences led by politicians and billion-dollar companies over the years, the threat of global warming and the carbon emissions spilling into the atmosphere have only risen. The 2022 United Nations Climate Change Conference, or Conference of the Parties of the UNFCCC, was the 27th United Nations climate change …

A hydro-powered crypto mining project based in Africa released an update on its efforts to bring energy developments to rural communities via Bitcoin (BTC). On Dec. 9, Gridless Compute tweeted photos and commentary on how their hydro-power BTC mining rigs are powering an entire rural settlement while also lowering energy rates for 2,000 people, the equivalent to 500 families. According to the tweet, costs decrease from $10 per month to $4. All of this while securing BTC’s underlying blockchain network. Powering a rural Kenya village and securing the #Bitcoin network with excess hydropower, all while lowering rates to 2000 people …

Although Bitcoin (BTC) mining remains a controversial topic, it’s becoming more common to hear how Bitcoin mining can help balance grid demand. This is being demonstrated in the state of Texas, as Bitcoin miners are able to participate in demand response programs, which incentivize miners to turn off their operations during peak demand. A spokesperson from the Electric Reliability Council of Texas (ERCOT) — the organization that operates Texas’s electrical grid — told Cointelegraph that crypto loads can have impacts on the grid just like any large load. Yet, they noted that crypto miners can help stabilize the grid by …

New York governor Kathy Hochul signed the proof-of-work (PoW) mining moratorium into law on Nov. 22, making it the first state in America to ban any PoW crypto mining activity for two years. The PoW mining moratorium will not only prohibit new mining operations but also refuse the renewal of licenses to those who are already operating in the state. Any new PoW mining operation in the state could only operate if it uses 100% renewable energy. The PoW mining bill was first passed by the state assembly in April earlier this year and later got the nod of the …

Bitcoin (BTC) has seen a 41% increase in energy consumption Year-on-Year (YoY) despite dramatic improvements in energy efficiency and a more diverse and sustainable energy mix — but there are concerns the rise could see regulators clamp down on mining. The data comes from a Q3 2022 report by the Bitcoin Mining Council (BMC) which represents 51 of the world's largest Bitcoin mining companies. The report found Bitcoin mining to consume 0.16% of global energy production, slightly less than the energy consumed by computer games according to the BMC — and an amount it considered to be “an inconsequential amount …

It’s another win for Bitcoin miners and the environment. A Dutch Bitcoiner has installed a Bitcoin (BTC) miner in a warehouse to replace the heating system powered by natural gas. Why? Because it’s cheaper, more environmentally friendly, and uses solar power. Our latest installation heats a warehouse with electricity instead of natural gas. We’ve installed manual valves to guide airflow. The sound has been attenuated under 40db with a large damper. The people that work in the warehouse enjoy the warm temperature and low sound. pic.twitter.com/fcdEUlqiuN — Bitcoin Brabant (@BitcoinBrabant) October 5, 2022 Bert de Groot is the founder of …

The Bitcoin (BTC) bashing has continued unabated even in the depths of a bear market with more research questioning its energy usage and impact on the environment. The latest paper by researchers at the department of economics at the University of New Mexico, published on Sept. 29, alleges that from a climate-damage perspective, Bitcoin operates more like “digital crude” than “digital gold.” The research attempts to estimate the energy-related climate damage caused by proof-of-work Bitcoin mining and make comparisons to other industries. It alleges that between 2016 and 2021, on average each $1 in BTC market value created was responsible …

While Ethereum (ETH) fans are enthusiastic about the successful Merge, Swan Bitcoin CEO Cory Klippsten believes the upgrade will lead Ethereum into a “slow slide to irrelevance and eventual death.” According to Klippsten, the Ethereum community picked the wrong moment for detaching the protocol from its reliance on energy. As many parts of the world are experiencing severe energy shortages, he believed the environmental narrative is taking the back seat. In an exclusive interview with Cointelegraph, Klippsten said “I think the world is just waking up to reality and Ethereum just went way off into Fantasyland at the exact wrong …
