Sanford School of Policy professor Billy Pizer outlines the challenges of designing policies that rein in the environmental impacts of energy use.
While it’s true that Earth’s temperatures and carbon dioxide levels have always fluctuated, the reality is that humans’ greenhouse emissions since the industrial revolution have put us in uncharted territory.

Thinking about solar power? This video – Understanding Solar – goes through the basic principles of residential solar energy. This is part one of my popular three-part video and article guide to going solar in Australia in 2022.
Chapters:
0:00 – Introduction
1:07 – How solar panels work
3:09 – Anatomy of a solar power system
10:40 – Solar system energy production
11:56 – How solar saves you money
13:22 – Batteries and solar
You can read the article version of this guide here:
*** Part 3: Owning Solar
Explains what to do after installing solar panels and how to make the most of your sytem. It also goes through what you should do to prepare for electric cars and home batteries.
And to get quotes from solar installers I have personally pre-vetted and trust: https://www.solarquotes.com.au/quote/

How do you use the sun to turn seawater into clean water? Desalination using solar energy will play a crucial role to solve water scarcity.
Already 4 billion people face water scarcity. Islands and coastal areas are vulnerable to droughts. The key to unlock extra fresh water lies in the sea. However, desalination is an expensive exercise, as much energy is needed and energy rates are high.
Technology company Elemental Water Makers has found a way to use the elements in their favour. Combining the power of the sea and sun, reliable access to clean water from unlimited resources is enabled. Using unique energy recovery technology, the amount of energy required is strongly reduced. Solar-powered desalination provides independence and resilience.
Coastal communities, lower lying atolls, private islands, private properties, resorts and municipalities can now get access to affordable clean water for generations to come.
Benefit from unlimited resources today and contact Elemental Water Makers for a free feasibility study:
The global food system is responsible for between 20-30% of greenhouse gas emissions, most of which are generated at the production stage. Take rice, for example, a food staple that is eaten regularly by over half the world’s population.
Conventional rice production generates emissions equivalent to the entire global aviation industry. So how can we produce rice in a way that uses fewer resources and regenerates nature? A growing number of farmers around the world are changing the way they produce rice, by adopting an agroecological approach called the System of Rice Intensification (SRI).
This method relies on a small group of simple interventions that together significantly reduces water use, methane production, and the use of chemicals, while providing better yields and reducing labour for rice farmers.
Multinational companies who support this type of agriculture through procurement and product design can address their scope 3 emissions and build resilience in their supplier communities.
According to Project Drawdown, SRI currently accounts for 4% of rice production. If this was increased to 25%, the emissions reduction would be equivalent to that which is currently generated by the whole of India.

Listen to Gry Johanne Åmodt present Statkraft’s low emission scenario, explaining how renewables can cut most of global greenhouse gas emissions in the coming years. Gry Johanne Åmodt is heading the Global Drivers unit in Statkraft, Europe’s largest renewable energy producer. Her job is to analyze and monitor the forces driving the renewable energy markets. Gry has been working at Statkraft since 2004 and has a Master’s degree in Industrial Economics from Norwegian University of Science and Technology (NTNU). This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
As far as our limited capacities are concerned, the sun is essentially an infinite and renewable energy source. It’s like a giant fusion reactor millions of miles away, illuminating the earth with as much energy as the whole of human civilization uses in a year! So, why aren’t we making more use of such a boundless source to solve all our energy-related problems?
Well, we’re actually pretty close to getting there, and in today’s video, I will show you how!
Solar photovoltaic panels are currently limited to a maximum efficiency of about 30%, and in practice only actually achieve about 20% to 23% efficiency. Now a team in Cambridge has developed a film that can amplify the number of photons that the panel can use, with a potential increase in efficiency to as much as 35%. So how do they do that?

In this video, we will discuss the use of drone technology in the solar industry for inspecting and maintaining photovoltaic systems. Solar PV systems are the world’s fastest-growing source of renewable energy, but concerns around how asset managers plan on maintaining these energy facilities poses a difficult question. What is the best cost-effective method for inspecting these PV systems that prioritizes safety, efficiency, and accuracy? The answer to this problem is drone technology.
Drones are revolutionizing every stage of the PV system lifecycle, from design, construction, commissioning, and maintenance. They are equipped with thermal imaging cameras that can identify solar anomalies such as cell hot spots, string outages, and reverse polarity. They can cover up to 50 megawatts per day and eliminate the need for plant downtime, making solar asset inspections more efficient than ever before.
Drones also provide a unique perspective that can be used to track the degradation of solar installations over time, and are safer for technicians as they are non-contact devices. Additionally, they provide an unmatched level of accuracy for data collection and analysis. Drones are increasingly being utilized by asset owners, EPC contractors, O&M teams, and OEM companies to fulfill their inspection needs.
