Aviation unites people, countries, society. Although I am not supporting that anyone flies at this time, I found some interesting information for those who must. CleanTechnica supports all those efforts to bring emission-free skies up to the standard being set by electric emission-free automobiles

It's clear to see that by increasing the penetration of electric vehicles every year, EV adoption will displace a significant amount of CO2 in Kenya. Kenya’s grid is already powered by a generation mix that is 93% renewable, thanks to significant contributions from geothermal, hydropower, wind, and some utility-scale solar plants. And since 39% of CO2 emissions in Kenya are from the transport sector, the transition to electromobility is the best route to reducing these emissions

A killer combo of food waste recycling, 3-D printing, and the biobased plastic alternative FLAM spells more trouble for oil and gas stakeholders

Pleasantly called natural gas and sold to many as a better solution, a good transition fuel, natural gas has been dominating new US electricity capacity alongside renewable energy. Yet, hydraulic fracking absolutely takes the "natural" out of it. Originally, natural gas was successfully sold as a cleaner transition fuel. Who knew there were not even laws on the books to address the hidden pollutants, and that there would be much information lacking about the truth of the acid stimulation, hydraulic fracturing, and other new extraction technologies

"Small-scale solar photovoltaics (e.g., rooftop solar systems) alone grew by 19.22% YTD. Compared to all other energy sources, solar-generated electricity has enjoyed the fastest growth rate thus far in 2019." Natural gas generation grew by 6.71%, nuclear energy generation grew by 0.8%, and coal-generated electricity generation declined by 14.46%

It seems like a lifetime ago when at the Rio Earth Summit in 1992, I watched more than 100 heads of state and government queue to sign the original documents of the Framework Convention on Climate Change, the Biodiversity Convention and Agenda 21. Negotiations had been tough, and some leaders were more enthusiastic than others

It is hard to build a net-zero building — one that produces more energy than it consumes — in the middle of a city. For one thing, nearby skyscrapers might block sunlight from reaching rooftop solar panels. For another, urban office buildings are cramped for space, and it generally isn’t possible to set up wind turbines on site

As 2019 comes to an end, we’re taking a step back to look at the videos about the climate crisis that caught the attention, and even inspired, Climate Reality followers

The Earth is rapidly approaching 1.5°C global warming, air pollution kills over 7 million people worldwide each year, and diminishing fossil fuel resources portend social instability. Yet, recently, world leaders at the United Nations Madrid climate talks failed to agree on a path forward. The core of the problem is the belief by some leaders that solving global warming will be expensive and drain the economy of their country. However, new research indicates that this belief is incorrect

On the 9th of this month, for the first time ever, Eskom, South Africa’s national power utility company, implemented Stage 6 Load shedding in which Eskom had to shed a load of 6000 MW to stabilise the grid. South Africa’s current installed capacity is 49.4 GW, according to the Draft Integrated Recourse Plan (2018) from South Africa’s Department of Energy

Sprint has indicated that it intends to source 100% renewable electricity and divert 50% of operational waste from landfills by 2025. This is what we need to hear on a day to day basis, from more and more corporations. While 2020 would be better, 2025 is not that far off, especially when you consider development timelines and corporate planning and budgeting challenges

One of CleanTechnica's first rate, well written, most fascinating articles this year was one by Maarten Vinkhuyzen, who wrote, "A perfect storm is brewing above the automotive industry. Three hardly grasped phenomena are working together. Just like a real storm, when the conditions align in the best/worst way, we get a devastating superstorm. These phenomena (or events) are the Osborne effect of delayed demand, the technology (cost) curve of battery prices and other technology, and the S-curve that describes market acceptance of new technologies."

Borrego Solar Systems and sPower worked with the Six Flags Discovery Kingdom this year to manifest the first theme park on the West Coast powered by solar energy. In this case, the solar will account for 80% of the park’s energy usage. One difference in this theme park's solar installation from other similar installations is that it will be powered by one of the most substantial solar carport installations in the country

A recent Solar Simplified survey dove into the topic of climate change and what we think we can do about it. Solar Simplified surveyed 5,000 people across the United States in order to understand their nuanced approaches, or lack of any approach, in daily life

Creative ways to prevent food waste, which is all too common and in a country where hunger is an issue, are being pursued by Google Kitchens. That's right, Google has kitchens. It has employees to feed and since Google is on a sustainability mission, its kitchens offer an innovative way to help with the issue of food waste

Californians love to be outside. But even on a clear, sunny day, we know that the air we are breathing isn’t as clean and clear as it looks, especially in our increasingly congested and crowded cities. Air quality is a complex topic that is affected by the weather, the time of day, and events like wildfires. But one aspect of air quality is very clear: tailpipe emissions make air quality worse. When those emissions happen in cities, millions of people are exposed to harmful pollution

CleanTechnica has been running a number of articles on little noted negative aspects of gas/diesel vehicles. These include hundreds of US deaths annually from carbon monoxide poisoning, oil refinery explosions, 137 US oil spills last year, what to do with old oil tankers, and the 150 gas/diesel car fires daily in the US. A common concept in Africa that is not noticed in the United States or other parts of the world is what in Africa is called “Africa’s Oil Curse.”

While the battle against coal-generated electricity is progressing nicely in the United States, Europe, South Korea, and even to a certain extent Japan, China, and India, the coal companies in some of those countries continue to have their sights on building more coal plants in Africa. Therefore, it is good news to learn that two Japanese banks, the Japan Bank for International Cooperation (JBIC) and the Nippon Export and Investment Insurance (NEXI), have withdrawn their support to finance two new 150 MW coal plants in Botswana, MorupuleB V and VI. The two coal plants were to be built by the Japanese company, Marubeni, in a joint venture with the South Korean firm, Posco Energy
