4_1   energy EFFICIENCY
is the ratio between the useful output of an energy conversion machine and the input, in energy terms.
The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat.

PARIS climate agreement is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation [Reduzierung] , adaptation and finance starting in the year 2020.
signed 04 2016
end 2017 195 UNFCCC members have signed the agreement [164 ratified it].
The contributions of the individual countries are called: NDCs - nationally determined contributions.
[CO2 emissions 2015: China 29.4%, US 14.3%, EEA 9.8%, India 6.8%, Russia 4.9%, Japan 3.5%, other 31.5%]

ARTICLE 3 requires them to be ambitious. Each further ambition should be more ambitious than the previous one, known as the principle of progression.
The specific climate goals are politically encouraged, rather than legally bound.
3_1.1 AIMS
A. Holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change;

B. Increasing the ability to adapt to the adverse [nachteilig] impacts of climate change and foster climate resilience [Belastbarkeit] and low greenhouse gas emissions development, in a manner that does not threaten food production;

C. Making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.“ Countries furthermore aim to reach „global peaking of greenhouse gas emissions as soon as possible“.

3_1.2 START 2018 [-2025]
The global stocktake will kick off in 2018 with a facilitative dialogue, evaluation in 2025.
[parties will evaluate nearer-term goal and and the long-term goal of achieving net zero emissions after 2050+.]

The negotiators of the Agreement, however, stated that the NDCs and the 2 °C reduction target were insufficient;
instead, a 1.5 °C target is required, noting „with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least-cost 2 °C scenarios but rather lead to a projected level of 55 gigatonnes in 2030“,
and recognizing furthermore „that much greater emission reduction efforts will be required in order to hold the increase in the global average temperature to below 2 °C by reducing emissions to 40 gigatonnes or to 1.5 °C“.
[in the first half of 2016 average temperatures were about 1.3 °C [although not the sustained temperatures over the long term which the Agreement addresses] .

Energy production is more efficient in a power plant than it is in a car engine.
_Burning natural gas in a power plant is about 60% efficient
_In a car, burning gas is less than 25% efficient, [vast majority of the energy lost to heat]

Nuclear fission

Nuclear fission
When the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed as nuclear fission.
This decay can be natural (spontaneous splitting by radioactive decay), or can actually be simulated in a lab by achieving necessary conditions (bombarding with neutrinos).
The resulting fragments tend to have a combined mass which is less than the original.
The missing mass is what is converted into nuclear energy in the above reaction.
An example of nuclear fission is the splitting of Uranium-235. The equation of the reaction has been given below.

U [235/92] + n [1/0]
Ba [144/56] + Kr [89/36] + 3 n[1/0]
