With the transformation of China's economy from high speed development to high quality development, the previous high energy consumption of the crude development method is being abandoned by all parties in the industry, energy saving and environmental protection is becoming a major trend in the development of most enterprises. On December 11, 2018, the United Nations Climate Change Conference was held, and energy efficiency and emission reduction became a hot topic again. The United Nations once proposed to respond to global climate change with the help of blockchain technology to achieve green energy saving and emission reduction. Facing the problem of global warming, what kind of role can blockchain play in the field of energy saving and environmental protection? Where exactly is the contribution of blockchain?
I. The era of green energy efficiency belonging to the blockchain
With the continuous acceleration of China's economic transformation, energy conservation and environmental protection, which was not recognized by everyone, has gradually become the focus of attention, and the country has also listed energy conservation as an important element of the medium- and long-term national economic and social development plan. According to the Energy Conservation Service Industry Committee of China Energy Conservation Association (EMCA), in 2017, the output value of the energy conservation service industry reached 414.8 billion yuan, 6,137 enterprises engaged in energy conservation services nationwide, 685,000 people engaged in the industry, contract energy management investment formed an annual energy saving capacity of more than 38 million tons of standard coal, and the annual carbon dioxide emission reduction exceeded 100 million tons, and the energy conservation service industry continued to maintain a good development momentum. The energy-saving service industry not only plays a vital role in the application of energy-saving technologies and investment in energy-saving projects in China, but also plays a positive role in promoting energy-saving transformation, reducing energy consumption, increasing social employment and promoting economic development, and has become one of the important graspers of China's transformation of the development mode, improving the quality and efficiency of the economy and building ecological civilization.
What exactly is the contribution that Internet technology can make in the area of energy efficiency? Compared to other technologies, blockchain and energy efficiency can be a no-brainer. For example, early blockchain projects that used the POW consensus mechanism consumed a lot of energy and produced large greenhouse gas emissions without generating value for the real economy. However, blockchain technology has gradually started to push the industry to evolve from the "high-energy blockchain" model to a comprehensive "energy-saving blockchain" direction over the years, expanding at a high speed in the field of energy saving.
Second, how can blockchain reconfigure the energy efficiency plateau?
The transformation of blockchain for the energy-saving industry does not start from the empowerment of the energy-saving industry, but from the change itself, which is the most different place when most Internet technologies are applied to the energy-saving industry, so the application of blockchain in the energy-saving industry is to change itself and empower the industry.
One is the blockchain's own energy-saving changes. For blockchain, the most important first step is to solve its own high energy consumption problem. Traditional blockchain requires all nodes to synchronize information together, which extremely consumes power resources and causes a great waste of energy. On this basis, the new generation of blockchain represented by Baidu Superchain has started to explore energy saving from the underlying network design and consensus mechanism by designing super computing nodes as well as supervisory nodes on the blockchain, improving the DPOD consensus and independently developing the TDPOS consensus, according to this algorithm, people holding passes across the network can vote for candidates, and the candidates selected by the final vote will participate in bookkeeping as super nodes, while others will act as supervisory nodes, which greatly reduces the cost. Only lower energy consumption is required to keep the entire blockchain network running and to enable the transfer of information, thus greatly reducing the energy consumption of the blockchain itself and achieving network-wide energy-saving development in the field of the blockchain's own development.
Second, to promote the process of industrial energy efficiency. After solving its own energy saving problems, as the US CSIS report shows, blockchain can achieve energy saving layout from the balanced smart grid through the supervision of industrial energy consumption at each stage, while the Chinese blockchain can learn from the US experience, with the blockchain distributed architecture, tamper-proof and collaborative consensus features, it can fully smart contract the problems in industrial energy saving, centralize the energy saving information scattered in different enterprises upstream and downstream of the industry, truly break the environmental data silos connected to the scattered energy saving field, and build a credible data monitoring and collection network covering the whole industrial chain and even the whole region. Then, by blockchaining and networking various aspects of energy consumption in industrial production, forming an information collection system through low-cost Internet of Things, breaking the black box of energy consumption in industrial production, allowing the monitoring of energy consumption to be collected and processed in stages, production links and supply chains, so that enterprises can effectively achieve energy saving and emission reduction in various production links. The union of blockchain and IoT can be used to reduce business costs as much as possible, thus driving energy efficiency.
Third, it promotes the upgrading of energy efficiency regulation. In addition to the enterprise's own energy saving and emission reduction, another important area of energy saving is the supervision of energy saving and emission reduction. As energy saving and emission reduction is often in the enterprise's own operation, it is often difficult for the supervisory department to effectively supervise the enterprise in real time, and more difficult to understand the most real situation. However this difficult problem in the traditional field has a different solution in the hands of blockchain. Blockchain can be applied to enterprises from raw material collection, operation and production, logistics and transportation, etc. Through the trusted consensus mechanism of blockchain, the energy consumption information of enterprises can be turned into tamper-proof data, which is authentically gathered from enterprises to the regulators. This will enable the regulator to know the real status of energy saving and emission reduction of enterprises at the first time, and even enable a quick recovery and determination of responsibility for energy saving and emission reduction, so as to better manage the problem of excessive energy consumption and waste.
Fourth, realizing a real carbon economy on the ground. All along, the state and academia have been exploring the management of energy saving and emission reduction by means of carbon emission rights, but the lack of real measurement of carbon emission data makes the carbon economy an unrealizable good idea, and in 2017 IBM launched a carbon asset management platform in China, which brings out the empowerment and tamper-proof of blockchain through a new superchain to blockchain carbon emission data directly, so as to promote the management of carbon emission rights, and even afterwards promote the construction of carbon trading market, and truly realize the carbon management of energy saving and emission reduction on the ground.
This unique way of blockchain first revolutionizing itself and then empowering the industry indicates an upgrade of the blockchain industry itself, the era of high energy blockchain is over and the era of green blockchain energy saving is coming much faster than we can imagine, let's wait and see.
