Hello Steven, Sure, natural gas is the most critical to displace, and solar +thermal storage is the right candidate for it. We are adding a 4th case : Natural gas--->boiler--->space to heat. Hopefully, in the future, this option will be eliminated either by law or by economics! or even better by people's ...

Hi, Storage question is essential for the energy transition so both the pro-clean energy and con-clean energy interpret it in a way that favors their position! Utility companies are worried about the uncertainties of their role in future decentralized power systems. Once the storage issue is solved to ...

Hi, Objectively I am in favor of thermal storage with water! Water-based thermal storage can be more efficient and more cost-effective than electric batteries for space heating applications in places where heat demand is high (Anchorage, Newyork city) and predictable (Schools, offices, shopping malls, ...

I totally agree, natural cooling/heating is the best option to consider first. Unfortunately, nowadays we are used to jumping on artificial tech to solve all problems, forgetting the natural way. This mindset goes beyond heating/cooling. Currently, in my hometown Ouaga for example, offices and schools ...

I would add a nuanced view about energy efficiency productivity for house heating. Energy efficiency can be productive for house heating in winter. In the figure below for example, the electric power of 1 kW could have been dissipated in the house directly (as TV, e-cooker, lighting heat dissipation) ...

Unfortunately when politicians are involved even 1+1 can take 2 years to solve! If smaller entities like cities, municipalities, electric cooperatives can become more independent in planning their energy future that could reduce drastically the blockades of some federal agencies that slow down the ...

Interesting topics out there ! I would see more work on the promotion of 1-community solar PV and 2-community-scale storage solutions 1-Community solar PV is an underestimated opportunity if we consider the number of families living in multi-floor buildings without sufficient space for PV panels. ...

RE: Energy Payback Metrics

Hi, Energy payback time for solar PV systems is dropping as more efficient cell manufacturing processes are developed. For rooftop PV systems, in 2004 an NREL document stated an energy payback time of less than 4 years for multi-crystalline based systems and 3 years for thin-film based systems. ( ...

Hi, This energy access program is a big opportunity for the private sector as it aims to achieve 100% electrification by 2030! There is a really nice tool "Integrated Energy Planning" in the link below that allows users to filter communities based on electrification needs, solar project estimated financial ...

Hi, As Scott said, the grid is becoming less reliable. With more tech going into the grid, it represents system operation improvement opportunities, however, there are also associated vulnerabilities that can be technical or man-made. Transitioning to 100% solar and wind (both intermittent ) without ...

Hi, First, storage is a necessity, not a choice. Besides the financial cost, the round-trip efficiency of the storage system can be around 80% so a nonnegligible amount of energy is lost. Electricity from PV or any other source must be used directly as much as possible to avoid losses during storage. ...
