Data centers consume a huge amount of energy and that number is increasing due to the increased production of data centers. A main component in the use of electricity is heat rejection. Typically, CRAC units are installed in the servers to reject heat to an chilled water loop. The problem is through redesign of data centers and different aging of equipment, the design might not be optimal for real world applications and heat rejection may not be occurring optimally.
Vigilent utilizes artificial intelligence to optimally control the CRAC units to provide cooling to the space. It automatically identifies hot spots in the server rooms and adjust the CRAC unit output accordingly to effectively eliminate the hot spot. Power is monitored for Measurement and Verification purposes and as a way to monitor the hot spots in the rooms.

Sustainability Issue: Air Pollution from Coal Burning Power Plants
In the United States, coal burning power plants emit 1.7 billion tons of CO2 into the atmosphere and are primarily responsible for climate change. Burning coal is the top source of CO2 emissions globally and a leading factor in smog, acid rain, as well as toxic air pollution.
Sustainable Technology Solution: Fossil-Fuel Free Power Plants
A power plant in the northwest of Stockholm, Sweden has committed to only burning renewable and recycled fuels in an effort to combat CO2 emissions that lead to global warming. Sweden is hoping to phase out fossil fuel use by the end of this decade and one method is by converting coal burning power plants to biofuels and garbage. The aforementioned plant, which is located in Vasteras, Sweden has started to work with the Swedish-based clothing store H&M who by law, must discard any clothing that has been contaminated with mold or does not meet the countries strict restrictions on chemicals. In 2017, the plant used 15 tons of discarded clothing from H&M. Although, most of their garbage-based fuel is supplied from the 400,000 tons of trash from neighboring towns and trash that is imported to the plant from areas in Great Britain. The plant currently provides energy to 50,000 households in Sweden and at its peak in 1996 it burned approximately 650,000 tons of coal. But, just last week, the last coal carrying ship came to Vasteras to supply the plant with just enough to last until 2020 when they will completely phase out their fossil burning furnace. They also recently added a wood-fired boiler to supplement the biofuel and trash burning units on the plant’s site.

Model system after plant in Vasteras, Sweden by phasing in biofuel and trash burning options with the addition of a wood-fired boiler on site.
In first year of implementation set goal of 20 tons of discarded materials from the clothing manufacturer and 100 tons of municipal trash.
If successful, set a goal of 10 years for full phase-out of fossil fuels.
Buildings typically operate on set schedules. Calculations and a lot of effort is done to optimize these schedules, but they don’t respond well to actual conditions. This can result in spaces that are over-ventilated, under-ventilated, too hot, or too cold at times. Additionally, building components performance drift over time and set points need to be adjusted accordingly.
Building IQ takes the building management data and uploads it to a cloud based server. From there, analytics are performed to optimize the setpoints and operating parameters of the system. This not only reduces the amount of energy used in these systems, but also increases the life time of the equipment as they are operating only as fast as necessary.
Work with control companies to find a platform of customers to develop pilot programs for installation. Get the utility companies to approve Measurement and Verification process to establish savings estimates. Next, have the utility companies issue prescriptive rebates for this type of installation. Finally, work with the controls company to install and run Building IQ at the sites.
“I spent 8 years in the Navy operating Nuclear Power Plants on an aircraft carrier. I love this idea. The biggest issue is getting the power from the plant to the shore, but if they can do it with wind turbines, they can do it with nuclear power.”
IBM Raises the Bar with a 50-Qubit Quantum Computer
IBM has developed a quantum computer that can handle 50 qubits per second. The computer IBM developed is still unstable, only preserving its state for 90 microseconds.
The world generates 2.5 exabytes of data every day . With the explosion of data being generated and preserved combined with billions of devices connecting to the internet, an issue the world will face is the ability to power all the machines and devices on a modern world. Rolf Landauer calculated and demonstrated that each bit operation of a computer requires a minimum amount of energy. With the amount of data being generated and saved, researchers are predicting the world will encounter energy issues to power all of our devices by 2040. The world’s fastest computer processes 33 Petaflops per second, which consumes 17.8 megawatts.
energy requirements of computers and devices will outpace ‘reasonable’ supply
volume of data requiring more processing time
Traditional computers store information in the form of a 1 or 0. As a result, traditional computers require energy and generate vast amounts of heat to perform complex calculations and operations. IBM’s development of a 50 -qubit quantum computer is 100 million times faster and consumes less energy than traditional computers. Quantum computers are able to store information as 1 and 0 simultaneously, vis-a-vis a feature of quantum mechanics known as superposition. The key feature of quantum computers is they can perform complicated calculations beyond the reaches of today’s computer while consuming less energy. Today’s computers can take days and weeks to calculate factors with hundreds and thousands of digits, which consumes vast amounts of energy. With IBM’s 50- qubit quantum computer, factors with 555 digits can be calculated within seconds.

Improvement in artificial intelligence (particularly deep learning)
This article touches on an important principle of ‘smart’ management of capital and resources within a generation blend, best exemplified by the classic saying, “if it ain’t broke… you still might be able to fix it.”
The EIA presents the value to be achieved in ‘repowering’ turbines, which is to say, upgrade them with newer, cheaper and more efficient technology while keeping the same turbine location, foundation, frame, etc.
This extends the life of the turbine by up to 20 years and can boost their efficiency by 25% (on average)
This is incentivised by the extension of the PTC (Production Tax Credit) for renewables, which applies to not only new renewables construction, but also renewables projects where at least 80% of the value is new construction: repowering often falls into this tranche so companies will elect to upgrade their wind fleet while saving on taxes.
GE has repowered up to 300 turbines for clients, and was recently awarded a contract for up to 700 more. Growth in this area is expected.
-Wind Power Installers and Contractors
-Regions and ISOs with wind power presence
-Consumers of electricity served by repowered turbines
1 – Continue to repower turbines with the most efficient modern turbine technology
2 – Look to incentivize all turbine owners to repower and claim PTC benefits, perhaps by raising awareness of the program.
3 – Look into writing specific policy to further incentivize repowering, such as state tax credits and rebates for contractor fees.
This is a great writeup of the benefits of offshore wind farms compares to onshore. One thing I would add is that there is a two-way street in terms of aesthetics and landscape: while less homeowners may object to the wind turbines being near their homes, there is still strong pushback from ocean life activists regarding sea floor damage, as well as people who oppose the sight of wind turbines in the ocean – this is why the Cape Wind project from a million years ago has still not gotten construction underway.
1) Sustainability Problem: Energy Use
70% of Electrical Production relies on fossil fuels and the USDA has predicted that by the 2030s electrical demand will increase by 40%. Currently, buildings use 40% of the electricity generated in the United States and this is expected to increase. Currently, photovoltaic technology, which uses sunlight to create energy, is gaining momentum as a form of renewable energy yet in order to harvest enough energy to run a commercial building, a huge swath of land must be employed. Roof-installed solar panels are not sufficient as their limited size also limits the amount of solar energy they can absorb.
1) Sustainable Technology: Solar Windows
Solar Windows Technology, Inc. has created a solution to energy production that would create acres of vertical solar farms in cities by installing solar paneled windows on skyscrapers and tall towers. They claim that this innovative technology would eliminate the need to use vast acres of land as a 50 story building could generate the same energy production as a 6-acre solar farm and allow for both electrical generation and energy banking. Solar Windows Technology, Inc is targeting towers and skyscrapers which consume about 40% of the energy generated for electricity in the United States. They claim that financial models show that these windows could save building owners 30-50% per year and installation would have a simple payback of 1 year. According to a recent article in Newsweek, “Researchers say transparent solar cell technology that harvests invisible wavelengths of light could meet nearly 100 percent of energy demand in the United States.” While there are still issues with efficiency of solar panels, and these windows are not immune to this problem, researchers are seeing improvements and they believe that approximately “5 billion to 7 billion square meters of glass surface in the United States could be used to meet 40 percent of the country’s energy demand, or “close to 100 percent” if energy storage is improved.”
3) Technology Stakeholder
Large Building Onwers
Solar Windows Technology Inc.
Identify a large city that has a sustainable energy problem they want to address.
Create a public-private partnership between the chosen city, sustainable investors, and Solar Windows Technology, Inc.
Create a multi-year timeline to roll-out solar window technology in 5 city-owned and operated buildings that have been monitoring their energy use for at least 5-10 years. This is essential to create baseline measurements.
Install in 2 buildings over first 6 month period.
Compare savings every 3 months after installation to the baseline measurements ensuring that the comparison covers the same period of the year (i.e. February compared to February).
After the first year, if energy savings are 30-50% as expected, roll-out to remaining 3 buildings. If the model is successful, create a policy for new construction and building retrofits for all city-owned buildings.
