The Global Energy & CO2 Status Report released by the International Energy Agency (IEA) makes the following observations:
- China, the US and India together accounted for nearly 70 per cent of the rise in energy demand and energy demand worldwide grew by 2.3 per cent last year.
- The rise in energy demand was driven by a robust global economy and stronger heating and cooling needs in some regions.
- Natural gas was the fuel of choice and it witnessed the biggest gains accounting for 45 per cent of the rise in energy consumption. Gas demand growth was especially strong in the US and China.
- Demand for all fuels increased and nearly 70 per cent of the demand growth was met through fossil fuels.
- Solar and wind generation witnessed a double-digit pace, with solar alone increasing by 31 per cent. But this was not fast enough to meet higher electricity demand around the world which resulted in increased use of coal.
- Global energy-related carbon dioxide emissions increased by 1.7 per cent to 33 gigatonnes (Gt) in 2018.
- Coal use in power generation surpassed 10 Gt and accounted for a third of the total increase.
- Majority of coal-fired generation capacity was concentrated in Asia, with 12-year-old plants on average, decades short of average lifetimes of around 50 years.
- Electricity continued to position itself as a fuel of the future, with global electricity demand growing by four per cent in 2018 to more than 23,000 terawatt hours.
- China remains the leader in renewables, both for wind and solar, followed by Europe and the US.
- Energy intensity improved by 1.3 per cent last year which was half the rate witnessed in the period between 2014 and 2016. This third consecutive year of the slowdown was the result of weaker energy efficiency policy implementation and strong demand growth in more energy intensive economies.
The findings are part of the IEA’s assessment of global energy consumption and energy-related carbon dioxide (CO2) emissions for 2018. The report provides a high-level and up-to-date view of energy markets, including the latest available data for oil, natural gas, coal, wind, solar, nuclear power, electricity and energy efficiency.
Railways form the backbone of the Indian Transportation System. The Railways has undertaken following measures under its Go Green initiatives:
- Ministry of Railways has planned to set up 1000 Mega Watt (MW) solar power by 2020-21. This would help Railways to source about 10% of its electrical energy from renewable source.
- Wind energy plants of 36.5 MW have been installed by the Railways.
- Almost all electrified Railway stations and 99% of service buildings have been fitted with 100% LED luminaries by Indian Railways to reduce power consumption.
- Railways have started blending of 5% bio-diesel in High-Speed Diesel (HSD) for diesel locomotives.
- 20% Compressed Natural Gas (CNG) substitution in diesel engines of Diesel Power Cars of Diesel Electric Multiple Unit (DEMU) trains and the introduction of solar energy based DEMUs.
- Tree plantation to increase green cover in Railway Premises.
- Water Audits at major consumption centres as well as the proliferation of Water Recycling Plants and Rain Water Harvesting (RWH) Systems as a step towards better water management.
- Assessment and rating of Indian Railway’s Production Units and major Workshops as Green Industrial Units.
- Nearly 163,000 bio-toilets have been installed in around 44,500 coaches.
- Increasing the pace of electrification to reduce the dependency on fossil fuels.
Also, the Ministry of Railways has taken a policy decision for allocating 1% cost in all sanctioned works for execution of environment-related works.
