Geothermal: Tapping Earth’s abundant energy

In the midst of controversy over B.C.’s Peace River Site C dam project, the Canadian Geothermal Energy Association released a study showing the province could get the same amount of energy more affordably from geothermal sources for about half the construction costs. Unlike Site C, geothermal wouldn’t require massive transmission upgrades, would be less environmentally disruptive and would create more jobs throughout the province rather than just in one area.

Despite the many benefits of geothermal, Canada is the only “Pacific Ring of Fire” country that doesn’t use it for commercial-scale energy. According to Desmog Blog, “New Zealand, Indonesia, the Philippines, the United States and Mexico all have commercial geothermal plants.” Iceland heats up to 90 per cent of its homes, and supplies 25 per cent of its electricity, with geothermal.

Geothermal energy is generated by heat from Earth’s rocks, liquids and steam. It can come from shallow ground, where the temperature is a steady 10 to 16 C, hot water and rocks deeper in the ground, or possibly very hot molten rock (magma) deep below Earth’s surface. As with clean-energy sources like solar, geothermal energy systems vary, from those that use hot water from the ground directly to heat buildings, greenhouses and water, to those that pump underground hot water or steam to drive turbines. The David Suzuki Foundation’s Vancouver and Montreal offices use geothermal.

According to National Geographic, geothermal power plants use three methods to produce electricity: dry steam, flash steam and binary cycle. Dry steam uses steam from fractures in the ground. “Flash plants pull deep, high-pressure hot water into cooler, low-pressure water,” which creates steam. In binary plants, which produce no greenhouse gas emissions and will likely become dominant, “hot water is passed by a secondary fluid with a much lower boiling point,” which turns the secondary fluid into vapour.

Unlike wind and solar, geothermal provides steady energy and can serve as a more cost-effective and less environmentally damaging form of baseload power than fossil fuels or nuclear. It’s not entirely without environmental impacts, but most are minor and can be overcome with good planning and siting. Geothermal fluids can contain gases and heavy metals, but most new systems recycle them back into the ground. Operations should also be located to avoid mixing geothermal liquids with groundwater and to eliminate impacts on nearby natural features like hot springs. Some geothermal plants can produce small amounts of CO2, but binary systems are emissions-free. In some cases, resources that provide heat can become depleted over time.Although geothermal potential has been constrained by the need to locate operations in areas with high volcanic activity, geysers or hot springs, new developments are making it more widely viable. One controversial method being tested is similar to “fracking” for oil and gas. Water is injected into a well with enough pressure to break rock and release heat to produce hot water and steam to generate power through a turbine or binary system.

Researchers have also been studying urban “heat islands” as sources of geothermal energy. Urban areas are warmer than their rural surroundings, both above and below ground, because of the effects of buildings, basements and sewage and water systems. Geothermal pumps could make the underground energy available to heat buildings in winter and cool them in summer.

New methods of getting energy from the ground could also give geothermal a boost. Entrepreneur Manoj Bhargava is working with researchers to bring heat to the surface using graphene cords rather than steam or hot water. Graphene is stronger than steel and conducts heat well. Bhargava says the technology would be simple to develop and could be integrated with existing power grids.

Unfortunately, geothermal hasn’t received the same level of government support as other sources of energy, including fossil fuels and nuclear. That’s partly because upfront costs are high and, as with oil and gas exploration, geothermal sources aren’t always located where developers hope they’ll be. As Desmog notes, resources are often found in areas that already have access to inexpensive hydro power.

Rapid advancements in renewable-energy and power-grid technologies could put the world on track to a mix of clean sources fairly quickly — which is absolutely necessary to curtail global warming. Geothermal energy should be part of that mix.

Hi :)

In America, July is the month that we celebrate our independence.

The first three weeks in July are ruled by the sun sign Cancer, so July carries ‘family’ energy. We barbecue, swim, gather with friends, and family, making memories and creating our versions of heaven.

The versions of ‘heaven’ that we are creating are the moments that, when we die, we will re-experience. So, when you wonder what a deceased loved one does with their time, when they’re not spending it around us, they are doing the things they loved the most.
They are ‘getting married’, or playing with their small children, celebrating Christmas, any moment that was one of the happiest days of their lives.  
So, make sure that you’re reveling in life, and building up your library of moments to re-visit when you die.
BIG NEWS, we have launched the all newAllisonDuBois.com. Much of the old content is still available. I am adding videos and new content each week.

Remembering the Moment, Enjoying Life: by Madisyn Taylor

It is only in the present moment that we experience being alive. 

Life, in all of its fullness, is happening right now. While our thoughts are sometimes elsewhere, beautiful opportunities and moments are being passed over and lost to the flow of time. And though we cannot possibly fully experience each leaf that falls to the ground, sometimes we get so attached to reaching our goals that we don’t pay attention to the wonder all around us. When we do that, we live in a world that exists only in our heads, while we miss life itself.

There is so much to be enjoyed and appreciated that we need to remember to pay attention to the present moment, because it is the only space in which we can experience being alive.We learn from our past, but dwelling on it keeps us from being fully present to life in the moment. We create our lives with our thoughts, but focusing so firmly on our imagined future keeps us from co-creating with the universe, so we might never allow ourselves to live our dreams as they manifest. It’s possible to be so happy and comfortable in our inner worlds that we lose touch with the business of life. We may enjoy spending large portions of time in meditation, or focused on our thoughts.

Life must be attended to, and if we are wise, we can enjoy it at the same time. We can awaken ourselves to the moment we are living right now by taking a deep breath and simply looking around. In doing so, we refocus our attention to our location in the real world. Then we can learn to appreciate the process of working toward our goals as much as their attainment. Balancing ourselves between the present moment and eternity, we can experience and enjoy the full range of reality available to us as spiritual beings living on earth.

Willingness to Feel
Opening to Understanding
by Madisyn Taylor

When we are resisting something based on a limited understanding, we must then open ourselves to willingness.

There are times when we may find ourselves struggling or even fighting with our thoughts and emotions. We may feel that something must be done in a certain way or not at all, or there may be some other situation that feels absolutely black and white. But life is not this way—it’s the way we are looking at our experiences that is causing the turmoil within us. When we become aware that the struggle we are having is with ourselves, we can turn our attention to the source in order to solve the problem, but we must be being willing to look where we need to and feel emotions that may make us uncomfortable at first. Then we can choose to really open ourselves to understanding all the options we can imagine. We are likely to discover that we are resisting something based on a limited understanding, and we must then open ourselves to willingness.

When we are willing to look at all the possibilities, we also become willing to accept that there is room for more than we can imagine. We can release ourselves from the grip we had on our emotions and stop limiting ourselves. We may have been unwilling to experience feeling loss, confusion, fear, or even joy for some reason or another, but when we realize that our understanding was limited we allow space for the universe to move in our lives.

Opening ourselves to willingness may feel like we are surrendering or abandoning all that we believed. But at the same time it is an act of power and courage because it is a conscious choice we make about how to apply our personal will. Being willing is to be in a state of willing something into creation. It is at once allowing ourselves to be while also choosing to direct our energy in a focused way. It is being and doing from a place of openness, where we can work with the universe rather than resist it. It is an open hand rather than one that is clenched into a fist. When we make a step toward willingness, we open ourselves to truth, possibility, and the movement of the wise universe in and through our lives.
