Renewable Energy Overview
Introduction
1 No.
2 Renewable energy provides about 10% of our needs.
3 Electricity and liquid fuel.
4 Yes
5 Efficiency and energy transportation.
6 Other renewables are limited by availability and location.
7
* Developing advanced technologies that capture energy more efficiently.
* A complete overhaul of the current infrastructure.
8 6%
9 We need __Super conductor_______________ materials.
10 We need _____ Lithium-ion______________ batteries. (what type?)
One promising solution is to convert solar energy into __ Chemical _____________ energy.

* Top scientific minds around the world are determined to find breakthroughs to these problems
* Governments and businesses have invested in technologies that harness the energy around us.
Environmental Impacts of Renewable Energy Technologies
* Less global warming
The use of non-renewable energy cause harm to the environment by releasing gases such as carbon dioxide, methane that are heavy contributors to global warming. Therefore, a switch to renewable energy will reduce the rate of global warming.
* Improvement in public health.
Renewable energy reduces breathing problems, neurological damage, heart attacks, cancer, and premature death linked to the excessive pollution of the environment by non-renewable energy.
* They are lasting.
Renewable energy such as winds, the sun, and water is inexhaustible as they are quickly replenished sources of energy.
* Economic benefits.
Renewable energy is more labor-intensive, meaning more jobs are created for each unit of electricity generated. Also, clean energy will cause a positive ripple effect to industries that deal with environmental pollution.
* Stable energy prices
Despite having a significant upward investment, renewable energy is low cost. Combined with the availability of energy, the prices can be sustained for an extended period.
* Reliability and resilience.
The rise of technological storage solutions means that renewable energy is easily implemented in more flexible grid systems.
What is CO2e?
1 This refers to calculating the potential of global warming of the energy sources through a life cycle assessment.
2 CO2e represents a standard ratio that converts other types of gases into the equivalent of CO2. Therefore, it is a more helpful measure because it includes other gases such as methane, nitrous oxide, and F-gases to measure fossil energy's overall impact on the environment.
Jobs and other economic benefits
Renewable energy.
Stable energy prices
Renewable energy.
Reliability and resilience
1 Renewable energy.
2
* Modular or decentralized systems are less prone to large-scale failure.
* The systems are spread over a large geographical area meaning severe problems like weather effects will not damage other infrastructure.
3 Renewable energy.
Barriers to Renewable Energy Technologies
1
* Capital cost.
Infrastructure for renewable energy is expensive. Water and wind energy are easy and cheap to operate; however, the bulk of the cost stems from the capital cost of installing infrastructure such as sola...
