Renewable energy sources are any source of electricity that can generate power without the use fossil fuels and other polluting sources. These include hydroelectricity and solar energy, as well as biomass. These technologies have the potential to become important players in the global climate change movement.
In the U.S., solar and wind energy are two of the most rapidly growing sources for electricity. These technologies are expected continue to grow globally. Wind resources are particularly abundant in the Appalachian Mountains and the Great Plains. Photovoltaics has the highest growth rate of any type of solar technology. By 2020, there will be 139 GW global capacity. In addition to providing electricity, these technologies can be used for low temperature heat and water heating.
Biomass is a versatile ingredient that has been used for cooking for thousands upon thousands of generations. You can get it from plant residues and agricultural waste. You can ferment it to make hydrogen and biodiesel.
Hydropower has long been harnessed. The power of water flowing in rivers is one source of electricity that has been around for a long time. It has been a reliable supply source in the past. Relying only on renewable energy comes with its challenges.
Grid integration of these technologies can be difficult due to the intermittent nature these sources. This is especially true when there are high levels of deployment. As the percentage of variable renewables increases, system costs increase as well.
Even though solar and wind are easy to use, it can be challenging to integrate these technologies into an existing grid. This is because of the need for backup generating capacity. It is also possible for weather conditions or the time of day to affect how much sunlight is available. The cost of technology and efficiency can also impact how much energy is consumed.
Wind and solar generation are expected to make up 29 percent of all global electricity generation by 2020. The increased use of these technologies will help to reduce carbon dioxide emissions, reducing the global carbon footprint.
Geothermal energy is an ancient source of heat. This source of heat has been used for space heating since the time of the Romans. Unfortunately, today it is not easily accessible. To reach this resource, enhanced geoothermal systems use fluid injection and advanced drilling techniques.
Wood is the most common type of biomass. It can be obtained from plants, trees, and municipal solid materials. Wood can be transformed into biofuels, like ethanol. Direct heating can be done with domestic hot water units.
These resources are being used in a number of countries. China and India have committed to building 78 GWe of capacity in 2030. This would result in a 9% decrease per capita CO2 emissions. Germany is home of some of Germany's largest power to-gas plants. This includes a 6 MW unit in the Energiepark Mainz as well as a 20-MW unit in Element Eins.
FAQ
What are some of the proposed solutions to climate change and how effective are they?
Climate change is a critical issue of our time, and requires the urgent attention of governments, businesses, citizens, and all other stakeholders. Rising temperatures, extreme weather events, increased sea levels, and melting polar ice are clear warnings of a disrupted climate system. To attempt to tackle this phenomenon, multiple proposed solutions have been put forward ranging from technological solutions, and behavioral changes to geoengineering.
Technological solutions: A wide range of technologies have been used to address climate change. These include renewable energy sources, such as solar or wind power. They provide reliable and clean energy with minimal impact on the environment. Electric cars powered with renewable energy could dramatically reduce pollution in cities and replace petrol vehicles. Reforestation projects are another technological option that aim to increase carbon sequestration, soil and trees. They also provide coastal protection systems to protect vulnerable areas from rising ocean levels.
Behavioral changes: Small adjustments to existing routines can make big differences in reducing emissions. This will help limit future climate disruption. For example, purchasing locally produced goods with shorter supply chains reduces emissions associated with transport costs for food. Also, using public or active transport instead of personal cars optimizes the use and reduces cost and air pollution. Additionally, home insulation that is more efficient can reduce dependence on gas boilers for heating your homes and lowers emissions.
Geo-engineering : Geo-engineering refers to large-scale interventions in natural system that have been deemed too risky for potential unforeseen results.
The effectiveness of these solutions is dependent on how much producers will invest in green alternatives. Electric Cars are more costly than petrol versions, but economic incentives favoring these green solutions play an integral role. Incentivizing alternative solution use via policy measures is one step forward. However this requires regulatory bodies willing to engage the players further.
What is the relationship between climate change and extreme weather events?
Global warming has directly affected extreme weather phenomena such as heatwaves. Global warming has contributed to an increase in the atmospheric temperature.
According to climate scientists, the frequency of extreme weather-related catastrophes has more than doubled in the past 20 years. Rising ocean water temperature causes sea levels to go up as well as changing wind patterns. This alters the normal distributions of storms, hurricanes, and other weather phenomena in different geographical areas around the globe.
2015 El Nino brought warm water towards South America. This led to increasing temperatures at an alarming pace and heavy rains that caused floods and displacement in Peru, Bolivia and other countries. Many places, including Antarctica had their highest-ever temperatures. This suggests a connection between global warming trends or the occurrence or frequency in extreme weather events.
Another example is Hurricane Irma, which struck in 2017, causing $50 billion in economic damage not only to Florida, but also to other states like Puerto Rico, Cuba, and others. This proves once again that climate change has been responsible for an increase in major storms.
The Intergovernmental Panel on Climate Change's (IPCC) concluded, "Human activities are increasing the severity current climate change." This naturally leads worldwide to more severe, intense, and frequent natural disasters. There is strong evidence of humans' involvement with extreme weather events occurring frequently around us all.
How can climate change impact food security and agriculture?
Global warming and climate change have an immediate impact on agriculture and food safety. The changing climate can affect rainfall patterns, temperatures, soil moisture levels, and extreme weather. This can impact farming activities, reduce crop yields, or cause loss of agricultural diversity. Warmer temperatures can increase the spread of diseases or pests that can impact crops and can also lead to shifts in the areas suitable for agriculture production. This can increase food production costs, as well as cause hunger and other nutritional problems worldwide.
Rising sea level poses a risk because they could flood agricultural land along many coasts, causing increased salinity to wetlands. Changes in climate also have an impact on livestock production. In summer, high temperatures can lower fertility rates in animals like sheep and cattle. This can result in lower milk yields, which can worsen food insecurity.
Global warming and climate change have a complicated relationship. However, adaptation strategies are being implemented by governments globally through strategic investments made in climate-smart farming (CSA). This includes promoting sustainable methods like crop rotation techniques and genetic diversity through conservation of native seed varieties. These help to protect against adverse impacts from extreme weather conditions and other environmental stressors due to the changing climate. In addition, CSA strategies call for reductions in greenhouse gas emissions through the use of renewable energy sources and the reduction of deforestation-related logging activities.
To ensure food security amidst a rapidly changing environment, it will be essential for farmers around the world to adopt technologies that are more sensitive to changes in the climate when it comes to selecting appropriate crops to grow on certain parcels of land. There must be improvements made to existing infrastructure in order to take the appropriate actions when critical crop thresholds fall. This includes installing stable irrigation networks that provide adequate access water at times when it is difficult for farmers to grow crops. For sustainable solutions to be created that will ensure the continued compliance with international dietary guidelines in our ever-changing climates, it is necessary to have a cohesive collaboration among all stakeholders. This includes government officials at international levels as well as NGOs located at local communities.
