- Sun
- Water (hydroelectricity)
- Wind
why does energy fuel the world economy?
Energy is needed at every step of the value chain.
what are the forces influencing the energy sector?
- markets
- technological innovations
- environmental concerns
- governments
in the short term, what are the factors that affect demand and supply of energy?
- Demand
- Economic cycles
- Climate variations
- Supply
- Geopolitical stress
- OPEC and other production and distribution monopolies
- Disruptions due to climate (E.g., hurricanes, earthquakes, ice
storms)
in the long term, what are the factors that affect demand and supply of energy?
- Demand
- Economic growth
- Population growth
- Industrialization
- Energy efficiency of production and goods (e.g. Kuznets curve)
- Durable goods consumption (Houses, cars, etc…)
- Trend towards a service-based economy
- Recycling
- Supply
- Exploration/Innovation
- Efficiency/Extraction
- Recycling
true or false: the demand for energy keeps growing
true
what region consumes the most energy?
asia by far
what is the second region to consume more energy?
North America and then europe
since when does asia consume more energy than north america?
2000
what areas have low demand for energy compared to their size?
africa, south asia and south and Central America
what were the three most used sources of energy used in 2023?
coal, oil and natural gas (oil is number 1)
what is the orimary source of energy for electricity?
coal and then gas
what is the region that consumes the most oil?
Middle East
what is the region that consumes the most natural gas?
CIS and Middle East
what is the region that consumes the most coal?
asia
what is the european trend on nuclear energy?
Output from nuclear in Europe fell by 1%, with the recovery of France’s nuclear fleet from prolonged outages in 2022 offset by Germany’s closure of its last three remaining units early in the year.
what is the chinese trend on nuclear energy?
China continues to lead the way in building new capacity. Since 2000 it has built around 60% of all new nuclear capacity additions. In late 2023, commercial operations began at China’s onshore small modular reactor (SMR) demonstration project, a world-first featuring the latest Generation IV technology and incorporating inherent safety systems.
what has been the japanese trend in nuclear energy?
Following the events in Fukushima in 2011, Japan has gradually returned units to service, and in 2023, output increased by 50%.
what has been the us trend in nuclear energy?
Whilst output from nuclear in the US remained relatively flat, it was still equal to the combined outputs of China and France, operators of the second and third-largest fleets.
what are the regions that have the most oil production?
middle east (31%)
north america (27%)
cis (15%)
what are the regions with the biggest oil consumption?
asia pacific (38%)
north america (22%)
europe (14%)
what are the top 5 oil-consuming countries?
us
china
india
russia
Saudi Arabia
when did the us turn into the largest oil producer?
2015
in 2013, what were the largest oil producer countries?
us
russia
canada
have oil reserves reached their peak?
New large sources of oil should be found to keep up
with demand in the future
Even if oil demand was
to remain flat to 2030,
45 mb/d of gross
capacity would be
needed just to offset
decline from existing
oilfields
energy is crucial for veleopment, but it can have side effects:
- Limited access to reliable and cheap electricity impairs investment and productivity.
- Effect of “dirty” energy on health and the environment.
- Productivity decline
- Climate change
how many people die worldwide from household pollution?
3.2 million per year (2019)
