We still don’t fully understand that fossil fuel and nuclear based energy conversion systems are a huge source of heat generation and, if Feynman and Maxwell are right, all this heat is conserved in the atmosphere of planet earth.
The crude oil industry is responsible for wasting (flaring) 140 billion m3 of natural gas every year!
For every single MWh (3,6 GJ) of electricity output from a nuclear power plant, triple the amount of heat is produced and released into the lower atmosphere and surface water through the cooling process.
Cooling does not destroy heat!
There is a tendency among people to set the bar as low as possible in order to achieve the desired solutions. In the global search for renewable energy it is not much different. We have set the bar too low!
Sustainable development requires high standards human health, strong efforts for empowerment, economics and for the conservation of nature.
Housing, hygiene, clean water, energy, health care and city development are the cornerstones for social engineering and governance.
One of the most important future socio-economic development goals is the empowerment of people in their own region. Mass migration from the past proves that human governance has failed to achieve this goal.
Migration of people is of all times. Today, the development of digital media plays an important role in the modern process of human migration. Migration has often an economic reason. Family live is torn apart and the economic development of the country site comes to a standstill.
Today, more people than ever live in a country other than the one in which they were born. In 2019, the number of migrants globally reached an estimated 272 million, 51 million more than in 2010. International migrants comprise 3.5 per cent of the global population. Compared to 2.8 per cent in 2000 and 2.3 per cent in 1980, the proportion of international migrants in the world population has also risen.
While many individuals migrate out of choice, many others migrate out of necessity. The number of globally forcibly displaced people topped 70 million for the first time in UNHCR’s almost 70 year history at the end of 2018. This number includes almost 26 million refugees, 3.5 million asylum seekers, and over 41 million internally displaced persons.
The UN Migration Agency (IOM) defines a migrant as any person who is moving or has moved across an international border or within a State away from his/her habitual place of residence, regardless of (1) the person’s legal status; (2) whether the movement is voluntary or involuntary; (3) what the causes for the movement are; or (4) what the length of the stay is.
The 2030 Agenda for Sustainable Development recognizes for the first time the contribution of migration to sustainable development. 11 out of the 17 Sustainable Development Goals (SDGs) contain targets and indicators relevant to migration or mobility. The Agenda’s core principle is to “leave no one behind,” not even migrants.

The city is an important human invention. An invention that proves that humans are social creatures. The way that we build our cities is a very important theme.
“What attracts people most, it would appear, is other people.”
“One felicity leads to another. Good places tend to be all of a piece – and the reason can almost always be traced to a human being.”
“It is difficult to design a space that will not attract people. What is remarkable is how often this has been accomplished.”
William H. (Holly) Whyte (1917-1999) is the mentor of Project for Public Spaces
Local economic development depends on the availability of abundant and affordable renewable energy and clean water. Natural intelligence based human creativity does the rest.
It is a fair conclusion that next to renewable energy, the availability of water plays a decisive role in future sustainable development. “Water rules all nature”
The ancient Roman solutions for water distribution looks expensive compared to the modern techniques that are available today. With the technological advancements over time, water technology is refined and simplified.
If we apply the same amount of economic effort to water preparation and distribution as we do for hard coal, natural gas and crude oil, we would not have potable water scarcity in the world.
Affordable renewable energy will almost automatically solve the worldwide water crisis. All the technology for water purification, desalination and distribution is available.
