In 2025, Onshore Wind and Large-Scale Solar Will Outperform Nuclear

According to the UK’s Department of Energy & Climate Change (DECC), the estimated future costs (in 2025) of onshore wind and large-scale solar power will be more competitive than that of nuclear power. As we can obviously notice, DECC's estimates for the same year were quite different just 3 or 6 years ago. It is good news for those countries who have to greatly increase the shares of low-carbon energy sources to satisfy the mitigation pledges manifested in their Intended Nationally Determined Contributions (INDCs; or now, their first Nationally Determined Contributions [NDCs]).

Note: If you want to know the current cost estimates of different energy technologies, please read my previous post (“Cost of Energy Comparison, Including Levelized Cost of Energy (LCOE) - 2016 Update” at http://j.mp/LCOE_2016).

Suicide Rates in Old Age: An International Comparison

I have compared elderly suicide rates among 34 countries. As we can easily observe from the figure below, South Korea’s elderly suicide rates are a big problem in the country.
In Korea, among 100,000 people who are 75 years old and over, 109 people committed suicide in 2009. The second-highest suicide rate in this comparison (42/100,000 in Hungary) is less than half of the tragic number.


Source: WHO (2014)
Note: All data (‘number of deaths’ and ‘age group population’) are from 2009, except Canada (2005) and United States of America (2007).


South Korea’s high suicide rates among elders might be partially caused by their poverty. Among OECD countries, South Korean elders suffer the most from destitution.

Life Expectancy and Energy Consumption: Countries and U.S. States - an Update

All of a sudden, I wanted to update my old post with the latest data. So I did using the year 2010 data. Below, I'm presenting a summary plot first, and then you can find the data table.
In general, as you can easily observe from the figure, longer-living people consume more energy. However, the U.S. states look different. The slope of the trend line is negative in the United States.
