COP21 – good news for the planet

Paris Climate Accord NDCs and Net Zero Pledges |  At COP21, commonly referred to as the Paris Climate Accord, nations sent representatives to pledge greenhouse gas emissions (GHGs) reduction targets (also known as Nationally Determined Contributions, or NDCs). At the annual Conference of the Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC), national dignitaries […]

Shortfall in International GHG Reduction Pledges

Is the World Going to Meet its Climate Targets? There is a substantial shortfall between GHG emission reduction pledges that almost 200 countries have made, and global climate reality. Worldwide, almost 200 countries have set climate targets - independently, and internationally all member-nations of the UNFCCC* have recommended targets. The international pledges are known as […]

Breakthroughs in Solar Photovoltaic (PV) and Solar Thermal Technology

Solar - the most abundant renewable energy on the planet | Recently there have been dramatic breakthroughs in solar energy that will help advance the mainstream use of photovoltaic (PV) technology. Here is a guide on top solar companies as well as in-depth explanations of various solar projects. This guide offers different recommendations depending on […]

Renewable Energy – Breakthroughs in Wind Energy

wind turbines Onshore Wind Farms - Cheap and Clean Energy | Onshore wind farms now provide the least expensive form of energy, renewable or non-renewable, once the wind farm is fully constructed and operational. Among energy sources used to power a municipal grid, wind farms also have the lowest greenhouse gas emissions (GHGs), and the lowest carbon […]

Economy vs. the Environment

Economic growth does not have to come at the expense of the environment. Sustainable technologies (such as renewable energy, energy efficiency, sustainable mass transit, electric vehicles) are also extremely beneficial to the economy. For example, the renewable energy industry employs over 500,000 people in the United States. The coal industry is responsible for under 90,000 […]
