Renewables vs. Nuclear

There are many reasons why renewable energy technologies do not receive as much financing and government support as nuclear energy. A major shortcoming of most renewable energy technologies is intermittency and a dependence upon the weather. Solar and wind projects develop models that predict how much energy they will produce over their useful life, but these models are based on weather forecasts and historical data that may not always be reliable. There are also often more energy-producing components in a typical renewable energy installation, like many solar panels or wind turbines, and if one or more of these components is not producing as it should, it can have a significant impact on the overall energy produced. This variability makes renewable energy a less appealing prospect for financing, which relies on the energy produced to repay the loan. Nuclear energy facilities are large, centralized producers that experience far less unanticipated variability in energy output. Nuclear facilities also have a longer operating history with more favourable performance than most renewable energy technologies, which makes the technology more mature and a safer investment.

In terms of government policy, renewable energy installations are often more expensive per unit of energy produced than nuclear facilities, and require larger land areas than nuclear. There is also a political component to the support of nuclear energy over renewables – many of the owners and developers of nuclear facilities are wealthy energy companies and utilities, which can provide more campaign donation contributions than more grassroots-oriented renewable energy companies.

Globally, there are a great deal of opportunities to apply renewable technologies in less developed areas where there is limited access to a national electric grid. The distributed nature of renewable technologies like solar power, geothermal, and biodigestor systems are ideally suited to rural villages in places like India and Africa. Island nations can also make great use of renewable technologies because their imported fuels costs are so expensive, that renewable technologies become cost competitive much more easily.

 

Marielle Martin – Lesson 3

The government has the ability to impose policy to incentives and disincentives certain behaviors. When it is a public goods issue, as this one is, imposing these policies is justifiable. A carbon tax is a large scale measure, being heavily analyzed at the present. Dale Jorgenson, and economist who studies the relationships between energy, policy, and environment, spoke in an interview about the tax. He (2014) noted that “a tax of $30 per metric ton of carbon dioxide is equivalent to a tax of 24.4 cents per gallon of gasoline”, which would “raise about $150 billion in revenue for the United States” (Shaw). The article also estimates the world’s yearly costs of climate change impacts to be around $1.6 trillion dollars (Shaw, 2014). With that in mind, the tax is actually hugely discounted to what we actually ‘owe’ the planet. In addition to the carbon tax, policies providing tax credits, grants, or home and business certifications based on energy use thresholds, high efficiency, or low emission/renewable energy source use could be applied. The metrics for these policies may be difficult to accurately measure though, as people have the ability to use a variety of energy options – only some of which require metering/grid connection that is monitored. As a last resort option, government policy could take a glance back in time to the 1970s. Oil economics and foreign power plays resulted in gasoline rationing in the United States. It’s a drastic measure, but there may be a day when such drastic measures are once again necessary. This type of government policy would surely ruffle some feathers over the issues of ‘freedom’ and ‘market economy’. It would span a much more diverse range of energy options to place restrictions on and have social implications on issues like income, standard of living, and access to alternatives.

To develop a business that works through government policy for energy efficiency, I would want to first identify where policy may be viable. I would be inclined to work on designing, building, or installing a measurement technology that could be used in policy aimed to incentivize household efforts for efficiency and minimizing consumption. As I mentioned above, measuring the metrics for which incentives would be rewarded can be difficult, so the prospect of policy only matters if the tools to provide the policy exist. In the hands of private business, innovative solutions for measuring a household’s energy use – even down to the type of energy – may be possible. In the UK, government is promoting smart meter installation in all homes and businesses by 2020 to increase energy conservation (Morris, 2014). The technology developed by Smart Metering Systems monitors gas and electricity consumption, sends the information to energy companies, and provides users with real consumption measurements (Morris, 2014). Smart Metering Systems’ profits have risen by 24% since government promotion began – proving that certain policy has the opportunity to create positive change (Morris, 2014). In addition to the initial energy conservation that users proactively achieve from smart meter installation, policy implementation to reward conservation efforts (by tax credit, grant, etc.) based on energy consumption ‘brackets’ would further increase energy conservation. For example, lower levels of energy consumption would correspond to higher levels of tax credit off of energy spending. The “kilowatt not used is the best of all” would definitely apply for a business working with government policy to conserve energy.
