[Home](https://www.safecoin.org/) 2. [Insights](https://www.safecoin.org/insights/) 3. Sustainability The Most Sustainable Cryptocurrency =================================== At SafeCoin people are all about efficiency, period --------------------------------------------------- We believe in global safety and security, we believe everyone has a role in protecting our environment. Safecoin was built from the ground up with energy efficiency in mind. With great performance comes great responsibility. By putting our communities and our environment first, anything is possible. On this page Energy usage comparison ----------------------- First of all let's have a look at the energy required for a single network transaction. [ ![](https://www.safecoin.org/fileadmin/_processed_/c/f/csm_2022-07_energy-consumption_network-transaction_f8304d8728.png) Visual comparison of kWh required for a single network transaction for SafeCoin, Solana, VISA, Ethereum and Bitcoin ](https://www.safecoin.org/fileadmin/_processed_/c/f/csm_2022-07_energy-consumption_network-transaction_0ce0c49f10.png "Visual comparison of kWh required for a single network transaction for SafeCoin, Solana, VISA, Ethereum and Bitcoin") SafeCoin greatly appreciates and admires Solana's technology and so the following energy comparison is based upon [Solana’s Energy Use Report: March 2022](https://solana.com/de/news/solanas-energy-use-report-march-2022). We also added VISA transaction details for a more relatable real-life comparison. | Activity | Energy Used | Factor | Costs[10](#c3006) | |---|---|---|---| | **A single SafeCoin transaction** | **0.00000025 kWh** | **x1** | **$0.00** | | A single Google Search[1](#c3006) | 0.0003 kWh | x1,200 | $0.00 | | A single Solana transaction[11](#c3006) | 0.00075194kWh | x3,007.76 | $0.00 | | One VISA transaction[12](#c3006) | 0,0014863 | 5945,2 | $0,00 | | Keeping an LED light bulb on for one hour[2](#c3006) | 0.01 kWh | x40,000 | $0.01 | | Using a fully-charged iPhone 13 on battery[3](#c3006) | 0.01241 kWh | x49,640 | $0.01 | | Working for an hour with a computer and monitor[4](#c3006) | 0.013 kWh | x52,000 | $0.01 | | One eth2 transaction[5](#c3006) | 0.035 kWh | x140,000 | $0.04 | | Watching an hour of television on a 40 inch+ LCD TV[4](#c3006) | 0.15 kWh | x600,000 | $0.15 | | Playing one hour of a PlayStation 5 game[6](#c3006) | 0.1969 kWh | x787,600 | $0.20 | | Running a refrigerator for one hour[4](#c3006) | 0.225 kWh | x900,000 | $0.23 | | One hour of central air conditioning[4](#c3006) | 3.5 kWh | x14,000,000 | $3.50 | | Using one gallon of gasoline[7](#c3006) | 33.7 kWh | x134,800,000 | $33.70 | | One Ethereum transaction[8](#c3006) | 192.45 kWh | x769,800,000 | $192.45 | | One Bitcoin transaction[9](#c3006) | 1483.91kWh | x5,935,640,000 | $1,483.91 | Fun Facts --------- Have you ever been involved in blockchain energy consumption discussions? Bitcoin and Ethereum are usually the main subjects, however it can be hard for one to wrap their head around the actual cost to power these blockchains. So, at your next dinner party you can mention some of these fun facts based upon our measurements. ![](https://www.safecoin.org/fileadmin/_processed_/0/c/csm_battery-full-solid_6a993cbc64.png) ### 17760 Transactions with a single battery A regular **AA Battery** with 0.00444 kWh (2.96Ah with 1.5V) capacity could power **17,760 SafeCoin transactions,** almost 6 Solana transactions, and 3 VISA transactions. Yet, for a single Bitcoin transaction, one would need at least 334,213 batteries. ![](https://www.safecoin.org/fileadmin/_processed_/1/7/csm_cc-visa-brands_c90accd12a.png) ### 232500000000 times Moving money globally The **232.5 billion VISA transactions per year** equate to more than **$2.7 billion USD in costs** at the average price of Electricity for industrial usage in the US (7.83$/kWh). With SafeCoin, this would only cost $455 million per year while with Bitcoin, one would need 12x the world's total electricity consumption to acheive this. *Sources: [https://usa.visa.com/ … aboutvisafactsheet.pdf](https://usa.visa.com/dam/VCOM/global/about-visa/documents/aboutvisafactsheet.pdf) * ![](https://www.safecoin.org/fileadmin/_processed_/c/7/csm_leaf-solid_b0148ef1de.png) ### Safe 98% of CO2 Emissions Assuming the equivalent of **0.85 pounds of CO2 emissions per kWh** (eia.gov), yearly VISA transactions contribute to about **146 million metric tons of greenhouse gas emissions** – equal to the 2020 traffic sector in Germany. By using SafeCoin, one could **reduce CO2 emissions by more than 98%!** Sources: [https://www.eia.gov/tools/faqs/faq.php?id=74&t=11](https://www.eia.gov/tools/faqs/faq.php?id=74&t=11) [https://www.umweltbundesamt.de/en/ … /germanys-greenhouse-gas-emissions-down-87-percent](https://www.umweltbundesamt.de/en/press/pressinformation/germanys-greenhouse-gas-emissions-down-87-percent) Initial Mainnet Benchmarking, 07.2022 ------------------------------------- To display third-party videos, we need your consent.

Running between 2000-3000 TPS at an average of 2800 TPS and measuring the power draw from a validator supporting the network. The average power during the test was determined to be approximately 56W. Solana's network runs at an average of 2000 TPS and has a baseline power draw of 1000W. From the initial tests, we can confirm SafeCoin has an energy efficiency of **approximately 0.00000025 kWh/txn compared to Solana at 0.000752 kWh/txn**. This makes SafeCoin the world's most energy efficient blockchain. **A quick basic rundown from our first test (much more data is coming):** **Units:** Watts - *W* | Joules - *J* | Transaction - *TXN* | Transactions per second - *TPS* | Kilowatt-hour - *kWh* 56 W = 56 J/s (56 J/s) / 2800 TPS = 0.02 J/TXN per validator **Our network currently consists of 45 active validators, so:** 45 validators \* 0.02 J/TXN per validator = 0.9 J/TXN for the entire SafeCoin network.***\*\**** 1 kWh = 3600000 J (0.9J/TXN) / (3600000 J/kWh) = 0.00000025 kWh/TXN ***\*\*Note:** These tests were conducted on an inefficient desktop whereas most of the active validators supporting the network run on servers which would likely reduce the energy consumptions even further.* --- 1\. “Did You Know ....
