Renewable Energy Solutions that Contribute to Energy Efficiency

Unlike fossil fuels, renewable energy does not emit CO2during power generation, and thus contributes significantly to the reduction of greenhouse gases through fossil fuel substitution. Wind and solar power generation are strongly required to minimize installation and maintenance costs while maximizing power generation efficiency. Our products contribute to the adoption of renewable energy by meeting this need.

For wind power systems, energy loss is inevitable because the generated power is converted from DC to AC when it is transmitted through an inverter circuit. Since most of this power loss is related to power devices, minimizing IGBT (Insulated Gate Bipolar Transistor) power loss directly leads to user system energy efficiency. Renesas IGBTs use our own low-power design expertise to reduce power losses by approximately 30% and contribute to overall system energy efficiency.

Today, manufacturers of solar power generation systems face two major challenges: miniaturization of equipment and higher functionality with the same substrate size, and stricter safety standards. Renesas will expand its portfolio of photocouplers and contribute to the widespread use of renewable energy by providing high insulation performance and safety in small size for high-voltage inverter control applications.

Air Quality Management Solutions for Building Automation

According to the IEA, building and other building-related CO2 emissions account for approximately 30% of global CO2 emissions, and in 2019, building-related energy efficiency investments totaled more than $150 billion. Our solution enables high performance CO2 sensing and fine air conditioning control to reduce power consumption.

Green and Super Green Devices

One of the pillars of Renesas' environmental activities is its eco-product activities. This is an activity to create environmentally friendly semiconductors, or eco-products, at all stages of the product life cycle, including product development, procurement, manufacturing, use, and disposal.

To create eco-products, we evaluate and index the environmental impact of our products in eight categories, including product safety and energy conservation, and compare them with our existing products. As a result of this product environmental assessment, developed products that have been certified as having superior environmental performance compared to our conventional products have been registered as Renesas Green Devices, while superior products have been registered as Super Green Devices, and are reported internally and externally.

Air Quality Measurement
High concentrations of ozone gas are a severe cause of environmental degradation and health risks, and are used in various air quality indicators in various countries and regions, including the Air Quality Index (AQI) of the U.S. Environmental Protection Agency (EPA). Renesas has expanded its outdoor air quality (OAQ) sensor platform, ZMOD4510, and has released an ultra-low-power ozone-sensing firmware. The latest firmware employs an AI-powered algorithm to selectively measure only ozone gas. The combination of ZMOD4510 and the latest firmware provides ultra-low power consumption of less than 200 μW, making it suitable for use in battery-powered devices. As a result, small mobile devices such as smartwatches, smartphones, and gas detectors can easily measure air quality, accelerating the spread of air quality measurement functions.

More Security for Mission-Critical Applications

According to a report by the World Health Organization (WHO), 1.35 million people worldwide have died in traffic accidents, and traffic accidents are one of the world's 10 leading causes of death. More than half of traffic fatalities occur among vulnerable road users (pedestrians, cyclists, motorcycles, tricycles and other passengers), and the development of safe vehicles has always been a global concern. The reduction of traffic accidents is one of the targets of the Sustainable Development Goals (SDGs), and the installation of the Advanced Driver Assistance System (ADAS) is becoming mandatory in each country including Japan.

Looking at IoT devices, Artificial Intelligence (AI) is revolutionizing our daily lives. Implementing AI requires real-time, high-volume information gathering and superior computing power to handle it, and IoT devices need to work together with the cloud more than ever before. Without robust cybersecurity measures in the IoT devices of the endpoints, the AI system itself could be cyber-attacked, with consequences for society at large.
