Renewable energy compare to nuclear power

As concerns about increasing populations and the environmental impacts of fossil fuels grow, the energy industry is looking for ways to evolve. Renewable energy and nuclear power both have the potential to be significant players in the next era of electricity generation. Each type of energy resource has its benefits and challenges, and both have their proponents.

Will nuclear or renewables be the answer to our energy woes? The issue isn’t quite so straightforward. We already use both, and comparing these two very different types of energy can get a bit messy. Circumstances vary from facility to facility, and opinions vary widely. However, we’ll do our best to break the differences down for you in this article.

You care deeply about our planet and are mindful of your carbon footprint, which is one of the reasons you might fantasize about things like triple-glaze windows and a geothermal energy system. Another reason — let’s not kid ourselves — is you’re fond of long-term savings.

For the short-term, however, you’re limited to eco-friendly improvements you can tackle yourself using basic materials.

We’ve got your back on this one. Below you’ll find 10 green home renovations for DIYers that are kind to the environment as well as your wallet — and just may lay the groundwork for higher-end upgrades down the road.

Geothermal vs. Solar Heating: Which Should You Install in Your Home?

March 26, 2018
geothermal vs. solar heating

“Green” home heating is the ultimate energy saver. Imagine the money you would save if you didn’t have to pay electricity or gas bills to keep warm — and think of the positive impact this change would have on the environment if whole communities switched to green energy.

If you are prepared to make a financial investment to convert your current heating system into environmentally friendly, renewable energy, you will have to decide between two major sources of energy: geothermal and solar.

Both are effective energy sources, and both are available. Each has its pluses and minuses, and one may be more applicable depending on where you live. Let’s take a look at geothermal vs. solar heating and see which is better for you.

Renewable Energy Installations Costs by State

March 12, 2018
renewable energy installation costs by state

Renewable energy differs slightly for each state. This can lead to confusion for homeowners who are looking to improve their homes and reduce their energy costs because a simple google search for green technology on homes doesn’t give you a solid picture. There are some similarities across borders though. Most states agree on the major components of what renewable energy is and include at least solar, wind, hydroelectric, geothermal, biogas and biomass.

This is far from an exhaustive list of renewable energy sources, but it covers the main ones that most homeowners are familiar with and have a high probability of trying to incorporate. Each one has a different kind of market, depending on location and availability. Even when working with the best possible options for an area, there are still substantial costs and challenges to overcome.

Cost Advantages of Rooftop Solar Panels vs. Grid Electricity

February 23, 2018
rooftop solar panels vs. grid electricity

Installing solar panels on your roof can significantly reduce your environmental impact and give you more control over the energy you use. The use of solar power has been spreading rapidly across the globe as it becomes more accessible to people.

The environmental benefits of solar power are clear, but how does it stack up regarding cost? Installing solar panels can reduce your energy costs, but installation costs and the amount you can save varies widely depending on where you live, rebate programs you’re eligible for, what type of technology you use and many other factors.

Let’s take a look at three cost advantages of installing solar panels on your property as compared to getting your energy from the grid.

propane vs geothermal

There are some great options available for heating your home, but two of the best options are propane and geothermal. Each one provides different benefits and has different drawbacks to it. Understanding the differences can help you make the best decisions for your situation. Propane vs. geothermal isn’t just about the cheapest option, though. You also have to take into account how it will affect the value of your home, how it will pay you back over the long-term and what kind of improvements in the area you can expect.

How Do Offshore Wind Farms Compare to Onshore Wind Farms?

January 29, 2018
Offshore wind farms compare to onshore wind farms

Picture a boat 7,000 years ago carrying pottery, iron tools and a fresh haul of fish from the Nile. Okay, now how is it moving? Wind, of course! Fast-forward 5,000 years to China in 200 B.C., and we see simple windmills used to pump water — once again, harnessing the impressive power of the wind.

While we are the first to commercially exploit the wind’s power on an industrialized scale, using the power of wind — and that of the other elements such as water and sun — is not a new concept. Nevertheless, the progression to today’s wind farms both on and offshore is striking.

In the UK alone, onshore wind farms have the capacity of more than 8,800 megawatts, and offshore farms have the capacity of over 5,000 megawatts. So how do wind farms produce all this energy? Let’s briefly go back to basics. Wind farms are made up of groups of wind turbines, located within relatively close vicinity to each other. More often than not, wind farms are home to hundreds of turbines across hundreds of square miles, and each one produces electricity.

Hydroelectricity 101: Should We Support this Form of Energy?

January 22, 2018

At first glance, hydroelectricity may seem like the ultimate renewable energy resource. It’s readily available, relatively inexpensive and uses natural resources to produce electricity. On the other hand, it can negatively impact marine life and their habitats, change the landscape and alter natural water flow patterns.

This Hydroelectricity 101 guide explains the basic process of how hydroelectricity works. Basically, hydroelectricity is the result of damming rivers. Water builds in a reservoir, creating a pressure differential. The pressure differential forces water through a penstock, which turns a turbine connected to an electric generator. Higher dams have more energy potential, since steeper penstocks create more energy.

The ocean also represents another potential form of hydroelectric power in the form of tide cycles and waves. In fact, coastal water resources have the potential to generate up to 1,000 terawatts of energy in the United States alone. Some offshore hydroelectric sources are in use, though at a much smaller scale compared to hydroelectric power.

Obama’s Environmental Legacy Versus the Legacy Trump Is Leaving

December 29, 2017
Obama's environmental legacy

Since the primordial cook fires of our ancestors first released carbon into the atmosphere, humans have made changes to their environment. Our surroundings, after all, are our vehicle for advancement: We learned breeding and farming to supply a steady food supply, cut trees from the forests for shelter, and burned whatever we could for heat and light. The Earth provides what we consume, fueling our collective forward motion.

Consumption and modification of the environment seat us at the forefront of all other species and allows us the luxury of meteoric advancement — often at the cost of our surroundings. Our progress has finally reached a terminal point where we, as a species, become aware of our unsustainable lifestyles. We may still use the Earth as elastic for the evolutionary slingshot of the human race, but our future seeks better propulsion by sustainable means.
