Key Facts

Greenhouse Gas

Energy is the dominant contributor to climate change, accounting for around 60 percent of total global greenhouse gas emissions.

Air Pollution

Indoor air pollution from using combustible fuels for household energy caused 4.3 million deaths in 2012, with women and girls accounting for 6 out of every 10 of these.

Energy

The share of renewable energy in final energy consumption has reached 17.5% in 2015.

I would absolutely do what we’ve done here again in a new facility.

Malcolm Nightingale - Operations Manager, Rooms To Go View Eneref Report

You definitely get that feeling of daylight in the hallways and the classrooms.

Phillip Williams - Energy Manager, Town of Ashland View Eneref Report

We looked for opportunities to leverage best practices within budget that are environmentally conscious.

Bill Anderson - VP Operations, Karndean Flooring View Eneref Report

When the renovation was complete, it was unbelievable. Students were astonished by the results.

Energy Distribution

The energy supply sector is the largest contributor to global greenhouse gas emissions. In the baseline scenarios assessed in AR5, direct CO2 emissions of the energy supply sector increase from 14.4 GtCO2 / yr in 2010 to 24 – 33 GtCO2 / yr in 2050 (25 – 75th percentile; full range 15 – 42 GtCO2 / yr), with most of the baseline scenarios assessed in AR5 showing a significant increase.

GHG emissions from energy supply can be reduced significantly by replacing current world average coal-fired power plants with modern, highly efficient natural gas combined-cycle (NGCC) power plants or combined heat and power (CHP) plants, provided that natural gas is available and the fugitive emissions associated with its extraction and supply are low or mitigated GHG emissions from energy supply can be reduced significantly by replacing current world average coal-fired power plants with modern, highly efficient natural gas combined-cycle (NGCC) power plants or combined heat and power (CHP) plants, provided that natural gas is available and the fugitive emissions associated with its extraction and supply are low or mitigated.

The energy supply sector converts over 75% of total primary energy supply (TPES) into other forms, namely, electricity, heat, refined oil products, coke, enriched coal, and natural gas. Industry (including non-energy use) consumes 84% of final use of coal and peat, 26 % of petroleum products, 47% of natural gas, 40% of electricity, and 43% of heat. Transportation consumes 62% of liquid fuels final use. The building sector is responsible for 46% of final natural gas consumption, 76% of combustible renewables and waste, 52% of electricity use, and 51 % of heat. Forces driving final energy-consumption evolution in all these sectors have a significant impact on the evolution of energy supply systems, both in scale and structure.

By 2010, Asia had become the major emitter with 41 % share. China’s emissions surpassed those of the United States, and India’s surpassed Russia’s (IEA, 2012f). Asia accounted for 79 % of additional energy supply sector emissions in 1990 – 2000 and 83 % in 2000 – 2010, followed well behind by the MAF and LAM regions.

limiting global warming to 1.5°C would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities. Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050. This means that any remaining emissions would need to be balanced by removing CO2 from the air.

Emission Trends and Drivers

Multiple options exist to reduce energy supply sector GHG emissions (robust evidence, high agreement). These include energy efficiency improvements and fugitive emission reductions in fuel extraction as well as in energy conversion, transmission, and distribution systems; fossil fuel switching; and low-GHG energy supply technologies such as renewable energy (RE), nuclear power, and carbon dioxide capture and storage.

Because the cost of energy from many (but not all) RE technologies has historically been higher than market energy prices, public R&D programmes have been important, and government policies have played a major role in defining the amount and location of RE deployment. Renewable energy currently constitutes a relatively small fraction of global energy supply, especially if one excludes traditional biomass. However, RE provided almost 21 % of global electricity supply in 2012.

Energy is central to nearly every major challenge and opportunity the world faces today. Be it for jobs, security, climate change, food production or increasing incomes, access to energy for all is essential. Working towards this goal is especially important as it interlinks with other Sustainable Development Goals. Focusing on universal access to energy, increased energy efficiency and the increased use of renewable energy through new economic and job opportunities is crucial to creating more sustainable and inclusive communities and resilience to environmental issues like climate change. 

At the current time, there are approximately 3 billion people who lack access to clean-cooking solutions and are exposed to dangerous levels of air pollution. Additionally, slightly less than 1 billion people are functioning without electricity and 50% of them are found in Sub-Saharan Africa alone. Fortunately, progress has been made in the past decade regarding the use of renewable electricity from water, solar and wind power and the ratio of energy used per unit of GDP is also declining. 

However, the challenge is far from being solved and there needs to be more access to clean fuel and technology and more progress needs to be made regarding integrating renewable energy into end-use applications in buildings, transport and industry. Public and private investments in energy also need to be increased and there needs to be more focus on regulatory frameworks and innovative business models to transform the world’s energy systems. 

  1. Does natural interior daylighting pay for itself?

    Lighting accounts for roughly one third of electricity used by commercial or educational facilities in the United States. Whereas natural interior daylight requires no energy beyond sunlight. And Natural interior daylight is about 10-times more efficient then rooftop PV cells for lighting a room.

  2. How do students preform under natural interior daylight?

Especially in learning environments, skylit classrooms provide a natural and stimulating space for teacher and student. While studies show that poor lighting adversely affects learning, daylighting has been proven to increase student performance in math and reading scores, as well as improving attendance. t button to change this text.

  4. How do office workers preform under natural interior daylight?

    Studies show that office workers have few sick days. The human performance numbers in daylighting systems are important because the ROI for daylighting installations can sometimes be a difficult sell. In fact, the human performance gains can outweigh the energy savings, where human performance can be measured in financial terms.
