Worldwide, transportation accounts for roughly a quarter of the total final energy demand and a similar share of energy-based carbon dioxide emissions (IEA, 2016f). The transport sector has the most homogenous of fuel mixes, with petroleum-based products accounting for roughly 95% of the overall final share (Kahn Ribeiro et al., 2012). Biofuels and other options, like electric vehicles, have the potential to displace a notable portion of petroleum and CO2 emissions in the transport sector. Global use of ethanol, the most widely used among biofuels, has grown significantly in recent years. Between 2000 and 2010 alone, ethanol utilization increased 350% worldwide, with trade increasing by a factor of 5 and usage equaling 74 billion liters in 2010 (Valdes, 2011). This chapter examines the underlying roots of the biofuels transition in Brazil. Two micro-shifts—one that is government- led and a second that is industry-led—are evaluated, demonstrating how a new, energy market and industry can develop at a national scale through the retooling of existing industries and infrastructure. Insights on policy inflections, market longevity, and dual-use technology are also covered. Brazil is the historical leader in biofuels and the only country to substantially alter its automotive fuel mix with ethanol, shifting from 1% in 1970 to 34% in 2014 (see the section entitled “Modern Transition” later in this chapter). Ranked sixth globally for its population of roughly 206 million people and eighth for its economy of $3.1 trillion in mid-2016 (CIA, n.d.), Brazil has been a leading pioneer in the production and export of ethanol, its principal biofuel. In 2015, Brazilian ethanol equaled 28% of the global supply (Renewable Fuel Association [RFA], 2016). The country is known for having the lowest production costs of ethanol (Goldemberg, 2008; Shapouri, and Salassi, 2006; Valor International, 2014). Brazil also has a unique distribution network of more than 35,000 fuel stations supplying the renewable fuel (Agência Nacional do Petróleo, Gás Natural e Biocombustíveis, 2008).

“Carbon Neutrality” means that enterprises, groups, or individuals calculate the total amount of greenhouse gas emissions produced directly or indirectly within a certain period and offset their Carbon dioxide emissions through afforestation, energy conservation, and emission reduction to achieve zero carbon dioxide emissions. Since 2020, the commitment to Carbon Neutrality has been paid attention to by various industries. Particularly, in the car industry, “Carbon Neutrality” has almost become one of the hottest directions. This paper focuses on policymaking and its impact on the automotive industry in the context of carbon neutrality. It is concluded that Carbon Neutrality is a problem that automobile enterprises must face. Automobile enterprises should set targets and time nodes related to Carbon Neutrality as soon as possible and speed up implementing specific measures. In addition, electric and new energy vehicles are more conducive to carbon emissions and carbon neutral transportation. Its development should also be put on the agenda.

The energy crisis and carbon dioxide emissions have become two of the most important problems in the world. As a very promising solution to these problems is the concept of Internet of Energy (IoE). The Internet of energy is a new energy generation paradigm that develops the revolutionary vision of an intelligent network, and tries to answer the question: how it is possible to achieve coordination and optimization in the macro-energy system.In this study we identify and systematize drivers that promote the implementation of IoE and identify the key benefits that can be obtained by implementing this system.
