IRENA and the UN: building renewable cities

Research conducted by IRENA has found that 65% of global energy requirements are derived from the demand of cities. Therefore, the energy transition from fossil fuels to renewables is crucial and could have long-term impacts of climate targets. Among the report’s materials were examinations of cities and what each one is doing to…

Cities are the engines of modern economic growth, supporting prosperity and opportunity, and are also a source of significant energy demands and of carbon emissions.

Francesco La Camera, Director-General of IRENA

Companies urged to embrace disruptive technology

Companies and governments have been urged to embrace disruptive technology, as it can contribute to decarbonizing energy and make it cleaner, greener and more accessible. Executives and experts attending the Africa Energy Indaba, in Cape Town, this week, outlined huge advances in electric vehicles, hydrogen production, processed heat, and energy…

In ten years’ time, most of us will have at least one form of battery and rooftop solar photovoltaic [system], which we will at times be consuming and at other times selling [electricity from].

New type of indoor solar cells for smart connected devices

The Internet of Things, or IoT, refers to a network of physical devices and applications connected through the internet. It is estimated that by 2025, many facets of our lives will be mediated through 75 billion IoT devices, a majority of which will be located indoors. Broad installation of such IoT devices requires the devices to become autonomous…

Ambient light harvesters provide a new generation of self-powered and smart IoT devices powered by an energy source that is largely untapped. The combination of high efficiency and low cost with non-toxic materials for indoor photovoltaics is of paramount importance to IoT sustainability.

Giant batteries, key to solar and wind power plans, start to get bank backing

Big batteries have long been touted as the future of the electrical grid and a key to unlocking solar and wind power. But when entrepreneur David Cieminis sought financing for a storage project in California, a state desperate to wean itself off of fossil fuels, he couldn’t reel in a bank…

A month or two ago, I wouldn’t have thought that they would have been interested.

Sustainable microgrids are the future of clean energy

Across the U.S., sustainable microgrids are emerging as a vital tool in the fight against climate change and increasingly common natural disasters. In the wake of hurricanes, earthquakes, and wildfires, the traditional energy grid in many parts of the country is struggling to keep the power flowing, causing outages that slow local…


Green Mountain Power’s pioneering steps in transactive energy raise big questions about DER’s value

The ultimate dream for distributed energy resources (DER) is “transactive energy” and a completely decentralized energy marketplace that allows transactions between all residential and commercial customers on the distribution system. Transactive energy is now done in wholesale power markets, but the transactions are enabled by system…

Transactive energy should derive optimum value from customer-owned or utility-owned assets. But value is not cost per kWh, it is the relative costs of keeping electricity flowing. On the distribution system, value is complex because of the magnitude of customers and assets.

Avista Utilities Electrical Engineering Fellow and Technology Strategist Curtis Kirkeby

Waste in the Renewable Energy Industry and How We Can Sustainably Power Our World

The renewable energy industry is relatively new in its processes, from production to disposal. In recent years, the installation of renewable energy, such as solar panels, has been heavily subsidized. In the United States, commercial and residential properties can receive a tax credit for implementing renewable systems. Policies such as this have…


Look to Africa, the mini-grid market is competitive

The REA of Nigeria is a Federal Government Agency established in 2006 under the Electric Power Sector Reform Act of 2005. It is saddled with the statutory mandate of stimulating Nigerian rural economy through the deployment of sustainable and reliable electricity solutions. Basically, we are dedicated to providing both on/and off-grid solutions by…

Africa is blessed with huge and largely untapped renewable energy potentials. Literature has it that the estimated power generation potential in the continent are 350GW for hydroelectric, 110GW for wind, 15GW for geothermal and a staggering 1,000GW for solar.

Executive Director, Rural Electrification Fund of Nigeria’s Rural Electrification Agency, Dr Sanusi Ohiare

OASC launches ‘guide to Synchronicity’

A guide to prepare cities for sustainable digital transformation and make it impactful for the public administration and citizens has been released. According to Open & Agile Smart Cities (OASC), The guide to Synchronicity is validated by 21 cities across Europe in a three-year project and has been adopted by more than 150 of its member cities…

To realize what digital transformation of cities and communities promises – saving resources, providing better services for citizens, enabling transparency – we must all act together and set the foundations now.

Martin Brynskov, chair of OASC and coordinator of the SynchroniCity project

ARE WE EMBRACING THE TRUE POTENTIAL OF SMART CITIES?

Smart cities are gaining traction, with worldwide spending on connected city initiatives predicted to reach $124 billion this year; an 18.9 percent increase from 2019. The smart city vision involves driverless cars, Artificial Intelligence (AI), smart street lighting and smart parking. It promises to solve a fundamental challenge for towns and cities – how to…
