gas field in the Gulf of Thailand supplies about 20% of Thailand's gas production. The field is estimated to have a capacity of 885 million cubic feet (c. 25 million m3) per day. Coal , Thailand had proved reserves of 1,063 million tonnes of sub-bituminous coal and lignite. In 2018, it produced 3.8 Mtoe, down 8.5% from 2017. It consumed 18.5 Mtoe in 2018, meaning it imported approximately 15 Mtoe. Its reserves-to-production ratio is 72 (years). Renewables Thailand's consumption of renewable energy in 2018 was 4 Mtoe, growing at a CAGR of 0.7% for the period 2008–2017. Biomass was the leading contributor of renewable energy, solar second, and wind third. Biofuels contributed 2119 Ktoe in 2018. The government is promoting the production of biodiesel from palm oil to be blended with conventional diesel with the aim of reducing petroleum imports. The production goal is 5.97 million liters per day in 2021. In March 2016, the Thai government gave approval for homes and commercial buildings to install solar panels. Each house will be permitted to generate 10 kW and each factory 40 kW. The private sector, despite Thailand's ample solar resources, previously had no right to install power-generation equipment. As of 2021, Thailand is considered as one of the most successful ASEAN countries in promoting and deploying solar energy. The Thai government wants all new cars sold to be electric by the year 2035. Despite progress and ambitious targets, improving renewable energy governance in Thailand is viewed as an important measure to attract more investment in renewable energy sources. Nuclear Thailand has no nuclear power plants. Earlier plans to produce five gigawatts of electricity by 2025 using nuclear technology were scaled back to 2 GW in the aftermath of the Fukushima disaster. As memories of Fukushima recede, interest in nuclear power has revived. Seven ASEAN nations, including Thailand, have signed cooperation agreements with Rosatom, Russia's state nuclear energy agency. EGAT is working with China, Japan, and South Korea on nuclear power generation technology and has sent 100 specialists to train for nuclear power plant projects. EGAT plans for up to five percent of the country's power generation to be generated from nuclear by 2036. Carbon emissions In 2018, Thailand emitted 302.4 Mt of CO2, up 0.8% over 2017, but down from its CAGR of 2.4% during the period 2007–2017. Electricity Ninety percent of Thai electrical generating capacity is conventional thermal. Oil-fired
